Lukas 4f7316c484 Add unified RequestValidationError handler to unify error response schema ...

- Add RequestValidationError handler that converts Pydantic validation errors to unified ErrorResponse format
- Ensures all error responses return consistent schema: code, detail, metadata, correlation_id
- Add field_errors count and first_field location to metadata for validation errors
- Register handler in exception handler hierarchy before HTTPException handler
- Add comprehensive tests for validation error responses
- Update Backend-Development.md documentation to include correlation_id field and validation error details
- All 44 error-related tests pass (38 existing + 6 new validation tests)
