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.
Introduce a new RSVP model to manage responses for events, including status, guest count, and additional details like dietary requirements.
