WIP: map route updates and custom item drag/drop fixes (broken)

- Fixed map header not updating in ItineraryTableViewWrapper using Coordinator pattern
- Added routeVersion UUID to force Map re-render when routes change
- Fixed determineAnchor to scan backwards for correct anchor context
- Added location support to CustomItineraryItem (lat/lng/address)
- Added MapKit place search to AddItemSheet
- Added extensive debug logging for route waypoint calculation

Known issues:
- Custom items still not routing correctly after drag/drop
- Anchor type determination may still have bugs
