Description

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.
