perf: optimize load_user_counts with DB-side aggregation

Replace Elixir-side counting with Ecto GROUP BY COUNT query for
better performance. This avoids loading all users into memory and
performs the aggregation directly in the database.

+
+## Overview & Scope
+
+### What We're Building
+
+A **basic CSV member import feature** that allows administrators to upload a CSV file and import new members into the system. This is a **v1 minimal implementation** focused on establishing the import structure without advanced features.
+
+**Core Functionality (v1 Minimal):**
+- Upload CSV file via LiveView file upload
+- Parse CSV with bilingual header support for core member fields (English/German)
+- Auto-detect delimiter (`;` or `,`) using header recognition
+- Map CSV columns to core member fields (`first_name`, `last_name`, `email`, `street`, `postal_code`, `city`)
+- **Import custom field values** - Map CSV columns to existing custom fields by name (unknown custom field columns will be ignored with a warning)
+- Validate each row (required field: `email`)
+- Create members via Ash resource (one-by-one, **no background jobs**, processed in chunks of 200 rows via LiveView messages)
+- Display import results: success count, error count, and error details
+- Provide static CSV templates (EN/DE)
+
+**Key Constraints (v1):**
+- ✅ **Admin-only feature**
+- ✅ **No upsert** (create only)
+- ✅ **No deduplication** (duplicate emails fail and show as errors)
+- ✅ **No mapping wizard** (fixed header mapping via bilingual variants)
+- ✅ **No background jobs** (progress via LiveView `handle_info`)
+- ✅ **Best-effort import** (row-by-row, no rollback)
+- ✅ **UI-only error display** (no error CSV export)
+- ✅ **Safety limits** (10 MB, 1,000 rows, chunks of 200)
+
+### Out of Scope (v1)
+
+**Deferred to Future Versions:**
+- ❌ Upsert/update existing members
+- ❌ Advanced deduplication strategies
+- ❌ Column mapping wizard UI
+- ❌ Background job processing (Oban/GenStage)
+- ❌ Transactional all-or-nothing import
+- ❌ Error CSV export/download
+- ❌ Batch validation preview before import
+- ❌ Dynamic template generation
+- ❌ Import history/audit log
+- ❌ Import templates for other entities
+
+---
+
+## UX Flow
+
+### Access & Location
+
+**Entry Point:**
+- **Location:** Global Settings page (`/settings`)
+- **UI Element:** New section "Import Members (CSV)" below "Custom Fields" section
+- **Access Control:** Admin-only (enforced at LiveView event level, not entire `/settings` route)
+
+### User Journey
+
+1. **Navigate to Global Settings**
+2. **Access Import Section**
+   - **Important notice:** Custom fields should be created in Mila before importing CSV files with custom field columns (unknown columns will be ignored with a warning)
+   - Upload area (drag & drop or file picker)
+   - Template download links (English / German)
+   - Help text explaining CSV format and custom field requirements
+3. **Ensure Custom Fields Exist (if importing custom fields)**
+   - Navigate to Custom Fields section and create required custom fields
+   - Note the name/identifier for each custom field (used as CSV header)
+4. **Download Template (Optional)**
+5. **Prepare CSV File**
+   - Include custom field columns using the custom field name as header (e.g., `membership_number`, `birth_date`)
+6. **Upload CSV**
+7. **Start Import**
+   - Runs server-side via LiveView messages (may take up to ~30 seconds for large files)
+   - Warning messages if custom field columns reference non-existent custom fields (columns will be ignored)
+8. **View Results**
+   - Success count
+   - Error count
+   - First 50 errors, each with:
+     - **CSV line number** (header is line 1, first data record begins at line 2)
+     - Error message
+     - Field name (if applicable)
+
+### Error Handling
+
+- **File too large:** Flash error before upload starts
+- **Too many rows:** Flash error before import starts
+- **Invalid CSV format:** Error shown in results
+- **Partial success:** Results show both success and error counts
+
+---
+
+## CSV Specification
+
+### Delimiter
+
+**Recommended:** Semicolon (`;`)  
+**Supported:** `;` and `,`
+
+**Auto-Detection (Header Recognition):**
+- Remove UTF-8 BOM *first*
+- Extract header record and try parsing with both delimiters
+- For each delimiter, count how many recognized headers are present (via normalized variants)
+- Choose delimiter with higher recognition; prefer `;` if tied
+- If neither yields recognized headers, default to `;`
+
+### Quoting Rules
+
+- Fields may be quoted with double quotes (`"`)
+- Escaped quotes: `""` inside quoted field represents a single `"`
+- **v1 assumption:** CSV records do **not** contain embedded newlines inside quoted fields. (If they do, parsing may fail or line numbers may be inaccurate.)
+
+### Column Headers
+
+**v1 Supported Fields:**
+
+**Core Member Fields:**
+- `first_name` / `Vorname` (optional)
+- `last_name` / `Nachname` (optional)
+- `email` / `E-Mail` (required)
+- `street` / `Straße` (optional)
+- `postal_code` / `PLZ` / `Postleitzahl` (optional)
+- `city` / `Stadt` (optional)
+
+**Custom Fields:**
+- Any custom field column using the custom field's **name** as the header (e.g., `membership_number`, `birth_date`)
+- **Important:** Custom fields must be created in Mila before importing. The CSV header must match the custom field name exactly (same normalization as member fields).
+- **Behavior:** If the CSV contains custom field columns that don't exist in Mila, a warning message will be shown and those columns will be ignored during import.
+
+**Member Field Header Mapping:**
+
+| Canonical Field | English Variants | German Variants |
+|---|---|---|
+| `first_name` | `first_name`, `firstname` | `Vorname`, `vorname` |
+| `last_name` | `last_name`, `lastname`, `surname` | `Nachname`, `nachname`, `Familienname` |
+| `email` | `email`, `e-mail`, `e_mail` | `E-Mail`, `e-mail`, `e_mail` |
+| `street` | `street`, `address` | `Straße`, `strasse`, `Strasse` |
+| `postal_code` | `postal_code`, `zip`, `postcode` | `PLZ`, `plz`, `Postleitzahl`, `postleitzahl` |
+| `city` | `city`, `town` | `Stadt`, `stadt`, `Ort` |
+
+**Header Normalization (used consistently for both input headers AND mapping variants):**
+- Trim whitespace
+- Convert to lowercase
+- Normalize Unicode: `ß` → `ss` (e.g., `Straße` → `strasse`)
+- Replace hyphens/whitespace with underscores: `E-Mail` → `e_mail`, `phone number` → `phone_number`
+- Collapse multiple underscores: `e__mail` → `e_mail`
+- Case-insensitive matching
+
+**Unknown columns:** ignored (no error)
+
+**Required fields:** `email`
+
+**Custom Field Columns:**
+- Custom field columns are identified by matching the normalized CSV header to the custom field `name` (not slug)
+- Same normalization rules apply as for member fields (trim, lowercase, Unicode normalization, underscore replacement)
+- Unknown custom field columns (non-existent names) will be ignored with a warning message
+
+### CSV Template Files
+
+**Location:**
+- `priv/static/templates/member_import_en.csv`
+- `priv/static/templates/member_import_de.csv`
+
+**Content:**
+- Header row with required + common optional fields
+- **Note:** Custom field columns are not included in templates by default (users add them based on their custom field configuration)
+- One example row
+- Uses semicolon delimiter (`;`)
+- UTF-8 encoding **with BOM** (Excel compatibility)
+
+**Template Access:**
+- Templates are static files in `priv/static/templates/`
+- Served at:
+  - `/templates/member_import_en.csv`
+  - `/templates/member_import_de.csv`
+- In LiveView, link them using Phoenix static path helpers (e.g. `~p` or `Routes.static_path/2`, depending on Phoenix version).
+
+### File Limits
+
+- **Max file size:** 10 MB
+- **Max rows:** 1,000 rows (excluding header)
+- **Processing:** chunks of 200 (via LiveView messages)
+- **Encoding:** UTF-8 (BOM handled)

+└─────────────────┘
+```
+
+### Technology Stack
+
+- **Phoenix LiveView:** file upload via `allow_upload/3`
+- **NimbleCSV:** CSV parsing (add explicit dependency if missing)
+- **Ash Resource:** member creation via `Membership.create_member/1`
+- **Gettext:** bilingual UI/error messages
+
+### Module Structure
+
+**New Modules:**
+- `lib/mv/membership/import/member_csv.ex` - import orchestration + chunk processing + custom field handling
+- `lib/mv/membership/import/csv_parser.ex` - delimiter detection + parsing + BOM handling
+- `lib/mv/membership/import/header_mapper.ex` - normalization + header mapping (core fields + custom fields)
+
+**Modified Modules:**
+- `lib/mv_web/live/global_settings_live.ex` - render import section, handle upload/events/messages
+
+### Data Flow
+
+1. **Upload:** LiveView receives file via `allow_upload`
+2. **Consume:** `consume_uploaded_entries/3` reads file content
+3. **Prepare:** `MemberCSV.prepare/2`
+   - Strip BOM
+   - Detect delimiter (header recognition)
+   - Parse header + rows
+   - Map headers to canonical fields (core member fields)
+   - **Query existing custom fields and map custom field columns by name** (using same normalization as member fields)
+   - **Warn about unknown custom field columns** (non-existent names will be ignored with warning)
+   - Early abort if required headers missing
+   - Row count check
+   - Return `import_state` containing chunks, column_map, and custom_field_map
+4. **Process:** LiveView drives chunk processing via `handle_info`
+   - For each chunk: validate + create member + create custom field values + collect errors
+5. **Results:** LiveView shows progress + final summary
+
+### Types & Key Consistency
+
+- **Raw CSV parsing:** returns headers as list of strings, and rows **with csv line numbers**
+- **Header mapping:** operates on normalized strings; mapping table variants are normalized once
+- **Ash attrs:** built as atom-keyed map (`%{first_name: ..., ...}`)
+
+### Error Model
+
+```elixir
+%{
+  csv_line_number: 5,       # physical line number in the CSV file
+  field: :email,            # optional
+  message: "is not a valid email"
+}
+```
+
+### CSV Line Numbers (Important)
+
+To keep error reporting user-friendly and accurate, **row errors must reference the physical line number in the original file**, even if empty lines are skipped.
+
+**Design decision:** the parser returns rows as:
+
+```elixir
+rows :: [{csv_line_number :: pos_integer(), row_map :: map()}]
+```
+
+Downstream logic must **not** recompute line numbers from row indexes.
+
+### Authorization
+
+**Enforcement points:**
+1. **LiveView event level:** check admin permission in `handle_event("start_import", ...)`
+2. **UI level:** render import section only for admin users
+3. **Static templates:** public assets (no authorization needed)
+
+Use `Mv.Authorization.PermissionSets` (preferred) instead of hard-coded string checks where possible.
+
+### Safety Limits
+
+- File size enforced by `allow_upload` (`max_file_size`)
+- Row count enforced in `MemberCSV.prepare/2` before processing starts
+- Chunking is done via **LiveView `handle_info` loop** (sequential, cooperative scheduling)
+
+---
+
+## Implementation Issues
+
+### Issue #1: CSV Specification & Static Template Files
+
+**Dependencies:** None
+
+**Goal:** Define CSV contract and add static templates.
+
+**Tasks:**
+- [ ] Finalize header mapping variants
+- [ ] Document normalization rules
+- [ ] Document delimiter detection strategy
+- [ ] Create templates in `priv/static/templates/` (UTF-8 with BOM)
+- [ ] Document template URLs and how to link them from LiveView
+- [ ] Document line number semantics (physical CSV line numbers)
+
+**Definition of Done:**
+- [ ] Templates open cleanly in Excel/LibreOffice
+- [ ] CSV spec section complete
+
+---
+
+### Issue #2: Import Service Module Skeleton
+
+**Dependencies:** None
+
+**Goal:** Create service API and error types.
+
+**API (recommended):**
+- `prepare/2` — parse + map + limit checks, returns import_state
+- `process_chunk/3` — process one chunk (pure-ish), returns per-chunk results
+
+**Tasks:**
+- [ ] Create `lib/mv/membership/import/member_csv.ex`
+- [ ] Define public function: `prepare/2 (file_content, opts \\ [])`
+- [ ] Define public function: `process_chunk/3 (chunk_rows_with_lines, column_map, opts \\ [])`
+- [ ] Define error struct: `%MemberCSV.Error{csv_line_number: integer, field: atom | nil, message: String.t}`
+- [ ] Document module + API
+
+---
+
+### Issue #3: CSV Parsing + Delimiter Auto-Detection + BOM Handling
+
+**Dependencies:** Issue #2
+
+**Goal:** Parse CSV robustly with correct delimiter detection and BOM handling.
+
+**Tasks:**
+- [ ] Verify/add NimbleCSV dependency (`{:nimble_csv, "~> 1.0"}`)
+- [ ] Create `lib/mv/membership/import/csv_parser.ex`
+- [ ] Implement `strip_bom/1` and apply it **before** any header handling
+- [ ] Handle `\r\n` and `\n` line endings (trim `\r` on header record)
+- [ ] Detect delimiter via header recognition (try `;` and `,`)
+- [ ] Parse CSV and return:
+  - `headers :: [String.t()]`
+  - `rows :: [{csv_line_number, [String.t()]}]` or directly `[{csv_line_number, row_map}]`
+- [ ] Skip completely empty records (but preserve correct physical line numbers)
+- [ ] Return `{:ok, headers, rows}` or `{:error, reason}`
+
+**Definition of Done:**
+- [ ] BOM handling works (Excel exports)
+- [ ] Delimiter detection works reliably
+- [ ] Rows carry correct `csv_line_number`
+
+---
+
+### Issue #4: Header Normalization + Per-Header Mapping (No Language Detection)
+
+**Dependencies:** Issue #3
+
+**Goal:** Map each header individually to canonical fields (normalized comparison).
+
+**Tasks:**
+- [ ] Create `lib/mv/membership/import/header_mapper.ex`
+- [ ] Implement `normalize_header/1`
+- [ ] Normalize mapping variants once and compare normalized strings
+- [ ] Build `column_map` (canonical field -> column index)
+- [ ] **Early abort if required headers missing** (`email`)
+- [ ] Ignore unknown columns (member fields only)
+- [ ] **Separate custom field column detection** (by name, with normalization)
+
+**Definition of Done:**
+- [ ] English/German headers map correctly
+- [ ] Missing required columns fails fast
+
+---
+
+### Issue #5: Validation (Required Fields) + Error Formatting
+
+**Dependencies:** Issue #4
+
+**Goal:** Validate each row and return structured, translatable errors.
+
+**Tasks:**
+- [ ] Implement `validate_row/3 (row_map, csv_line_number, opts)`
+- [ ] Required field presence (`email`)
+- [ ] Email format validation (EctoCommons.EmailValidator)
+- [ ] Trim values before validation
+- [ ] Gettext-backed error messages
+
+---
+
+### Issue #6: Persistence via Ash Create + Per-Row Error Capture (Chunked Processing)
+
+**Dependencies:** Issue #5
+
+**Goal:** Create members and capture errors per row with correct CSV line numbers.
+
+**Tasks:**
+- [ ] Implement `process_chunk/3` in service:
+  - Input: `[{csv_line_number, row_map}]`
+  - Validate + create sequentially
+  - Collect counts + first 50 errors (per import overall; LiveView enforces cap across chunks)
+- [ ] Implement Ash error formatter helper:
+  - Convert `Ash.Error.Invalid` into `%MemberCSV.Error{}`
+  - Prefer field-level errors where possible (attach `field` atom)
+  - Handle unique email constraint error as user-friendly message
+- [ ] Map row_map to Ash attrs (`%{first_name: ..., ...}`)
+
+**Important:** **Do not recompute line numbers** in this layer—use the ones provided by the parser.
+
+---
+
+### Issue #7: Admin Global Settings LiveView UI (Upload + Start Import + Results + Template Links)
+
+**Dependencies:** Issue #6
+
+**Goal:** UI section with upload, progress, results, and template links.
+
+**Tasks:**
+- [ ] Render import section only for admins
+- [ ] **Add prominent UI notice about custom fields:**
+  - Display alert/info box: "Custom fields must be created in Mila before importing CSV files with custom field columns"
+  - Explain: "Use the custom field name as the CSV column header (same normalization as member fields applies)"
+  - Add link to custom fields management section
+- [ ] Configure `allow_upload/3`:
+  - `.csv` only, `max_entries: 1`, `max_file_size: 10MB`, `auto_upload: false`
+- [ ] `handle_event("start_import", ...)`:
+  - Admin permission check
+  - Consume upload -> read file content
+  - Call `MemberCSV.prepare/2`
+  - Store `import_state` in assigns (chunks + column_map + metadata)
+  - Initialize progress assigns
+  - `send(self(), {:process_chunk, 0})`
+- [ ] `handle_info({:process_chunk, idx}, socket)`:
+  - Fetch chunk from `import_state`
+  - Call `MemberCSV.process_chunk/3`
+  - Merge counts/errors into progress assigns (cap errors at 50 overall)
+  - Schedule next chunk (or finish and show results)
+- [ ] Results UI:
+  - Success count
+  - Failure count
+  - Error list (line number + message + field)
+  - **Warning messages for unknown custom field columns** (non-existent names) shown in results
+
+**Template links:**
+- Link `/templates/member_import_en.csv` and `/templates/member_import_de.csv` via Phoenix static path helpers.
+
+---
+
+### Issue #8: Authorization + Limits
+
+**Dependencies:** None (can be parallelized)
+
+**Goal:** Ensure admin-only access and enforce limits.
+
+**Tasks:**
+- [ ] Admin check in start import event handler
+- [ ] File size enforced in upload config
+- [ ] Row limit enforced in `MemberCSV.prepare/2` (max_rows from config)
+- [ ] Configuration:
+  ```elixir
+  config :mv, csv_import: [
+    max_file_size_mb: 10,
+    max_rows: 1000
+  ]
+  ```
+
+---
+
+### Issue #9: End-to-End LiveView Tests + Fixtures
+
+**Dependencies:** Issue #7 and #8
+
+**Tasks:**
+- [ ] Fixtures:
+  - valid EN/DE (core fields only)
+  - valid with custom fields
+  - invalid
+  - unknown custom field name (non-existent, should show warning)
+  - too many rows (1,001)
+  - BOM + `;` delimiter fixture
+  - fixture with empty line(s) to validate correct line numbers
+- [ ] LiveView tests:
+  - admin sees section, non-admin does not
+  - upload + start import
+  - success + error rendering
+  - row limit + file size errors
+  - custom field import success
+  - custom field import warning (non-existent name, column ignored)
+
+---
+
+### Issue #10: Documentation Polish (Inline Help Text + Docs)
+
+**Dependencies:** Issue #9
+
+**Tasks:**
+- [ ] UI help text + translations
+- [ ] CHANGELOG entry
+- [ ] Ensure moduledocs/docs
+
+---
+
+### Issue #11: Custom Field Import
+
+**Dependencies:** Issue #6 (Persistence)
+
+**Priority:** High (Core v1 Feature)
+
+**Goal:** Support importing custom field values from CSV columns. Custom fields should exist in Mila before import for best results.
+
+**Important Requirements:**
+- **Custom fields should be created in Mila first** - Unknown custom field columns will be ignored with a warning message
+- CSV headers for custom fields must match the custom field **name** exactly (same normalization as member fields applies)
+- Custom field values are validated according to the custom field type (string, integer, boolean, date, email)
+- Unknown custom field columns (non-existent names) will be ignored with a warning - import continues
+
+**Tasks:**
+- [ ] Extend `header_mapper.ex` to detect custom field columns by name (using same normalization as member fields)
+- [ ] Query existing custom fields during `prepare/2` to map custom field columns
+- [ ] Collect unknown custom field columns and add warning messages (don't fail import)
+- [ ] Map custom field CSV values to `CustomFieldValue` creation in `process_chunk/3`
+- [ ] Handle custom field type validation (string, integer, boolean, date, email)
+- [ ] Create `CustomFieldValue` records linked to members during import
+- [ ] Update error messages to include custom field validation errors
+- [ ] Add UI help text explaining custom field requirements:
+  - "Custom fields must be created in Mila before importing"
+  - "Use the custom field name as the CSV column header (same normalization as member fields)"
+  - Link to custom fields management section
+- [ ] Update CSV templates documentation to explain custom field columns
+- [ ] Add tests for custom field import (valid, invalid name, type validation, warning for unknown)
+
+**Definition of Done:**
+- [ ] Custom field columns are recognized by name (with normalization)
+- [ ] Warning messages shown for unknown custom field columns (import continues)
+- [ ] Custom field values are created and linked to members
+- [ ] Type validation works for all custom field types
+- [ ] UI clearly explains custom field requirements
+- [ ] Tests cover custom field import scenarios (including warning for unknown names)
+

+
+## Rollout & Risks
+
+### Rollout Strategy
+- Dev → Staging → Production (with anonymized real-world CSV tests)
+
+### Risks & Mitigations
+
+| Risk | Impact | Likelihood | Mitigation |
+|---|---:|---:|---|
+| Large import timeout | High | Medium | 10 MB + 1,000 rows, chunking via `handle_info` |
+| Encoding issues | Medium | Medium | BOM stripping, templates with BOM |
+| Invalid CSV format | Medium | High | Clear errors + templates |
+| Duplicate emails | Low | High | Ash constraint error -> user-friendly message |
+| Performance (no background jobs) | Medium | Low | Small limits, sequential chunk processing |
+| Admin access bypass | High | Low | Event-level auth + UI hiding |
+| Data corruption | High | Low | Per-row validation + best-effort |
