fix(bookings): client test failures after map overlay refactor

- Make useEndpointPane tolerant when map mock lacks getPane/createPane
- Add useMapEvents to react-leaflet mock in MapView.test
- Rewrite RESMODAL-042 to use the new AirportSelect flow (airline and
  flight number only; airport codes are now saved as endpoints, not
  metadata)
