refactor: add proper types for all database insert operations

- Add missing Select and Insert types for Auth.js tables (Account, Session, VerificationToken)
- Update all insert operations to use typed New* variables:
  - NewUser for user signup
  - NewItem for adding wishlist items
  - NewSavedWishlist for saving wishlists
- Improves type safety and catches insert errors at compile time
