 - **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.
-- **Value Validation:** Custom field values are validated according to the custom field type:
-  - **string**: Any text value (trimmed)
-  - **integer**: Must be a valid integer (e.g., `42`, `-10`). Invalid values will cause a row error with the custom field name and reason.
-  - **boolean**: Accepts `true`, `false`, `1`, `0`, `yes`, `no`, `ja`, `nein` (case-insensitive). Invalid values will cause a row error.
-  - **date**: Must be in ISO-8601 format (YYYY-MM-DD, e.g., `2024-01-15`). Invalid values will cause a row error.
-  - **email**: Must be a valid email format (contains `@`, 5-254 characters, valid format). Invalid values will cause a row error.
