refactor(itinerary): replace CustomItineraryItem with ItineraryItem across codebase

- Update CKModels.swift to remove deleted type references
- Migrate LocalCustomItem to LocalItineraryItem in SavedTrip.swift
- Update AppDelegate to handle subscription removal
- Refactor AddItemSheet to create ItineraryItem with CustomInfo
- Update ItineraryTableViewController and Wrapper for new model
- Refactor TripDetailView state, methods and callbacks
- Fix TripMapView to display custom items with new model structure

This completes the migration from the legacy CustomItineraryItem/TravelDayOverride
model to the unified ItineraryItem model with ItemKind enum.
