Enhanced test coverage includes `repr` methods, model functionality, and validation logic for key models like `GiftItem`, `GiftCategory`, `EventMedia`, `RSVP`, and `GiftPurchase`. Refactored and added fixtures to support comprehensive testing scenarios. Addresses validation for gift reordering and updates `EventMedia` representation format for consistency.
Introduce a `validate_display_order` method to ensure a default value of 0 for `display_order`. Extend testing infrastructure with fixtures and unit tests for `EventMedia` to validate properties, metadata, and default behaviors.
Rename metadata fields for clarity and fix imports.
Updated metadata-related field names across models to improve clarity and consistency (e.g., `metadata` to `media_metadata` and `notification_metadata`). Fixed an error in `guest_gifts` metadata reference and added a proper imports initialization in `__init__.py` for all models.
```
Introduce EventMedia for managing media files linked to events, including file metadata, purpose, and relationships. Add GiftCategory to categorize gifts, featuring unique constraints, display options, and utility methods for handling related gifts.
