feat: implement trip incident dashboard, drop-off geofence validation, and calendar updates

- **Trip Incidents**: Created the `AdminTripController@incidents` API endpoint, built the `incidents.blade.php` view, enabled the incidents sidebar link, and added test coverage (`TripIncidentDashboardTest.php`).
- **Drop-off Points (LGU Geofence)**: Added a Barangay (LGU) dropdown to the drop-off point form. Integrated `Turf.js` to render the LGU boundary polygon on Leaflet and restrict pin placement (clicks, drags, and address search) to within the selected boundary.
- **Trip Calendar**: Changed the shortcut for opening the Daily Digest from Ctrl+Click to Shift+Click on calendar dates.
- **API fixes**: Corrected the Barangay fetch endpoint to `/api/v1/geo/barangays` in the Drop-off points view.
