Separated ErrorResponse and ValidationErrorResponse types:
- ErrorResponse: general errors (401, 403, 404, 500) - no field attribute
- ValidationErrorResponse: form validation errors (400) - includes field attribute
Updated respondValidationError to return appropriate type based on error format.
Updated Swagger documentation to use ValidationErrorResponse only for validation endpoints.
This ensures the field attribute only appears in API responses for actual form field validation errors, not in general error responses.
