Add quantity column to GuestGifts table and update references

Introduced a `quantity` field to track the number of reserved gifts in the many-to-many GuestGifts table. Updated all related CRUD operations, models, and imports to reflect the added column. Replaced `guest_gifts` with `GuestGifts` for consistency in naming conventions.
