Subject: feat(track): implement GPS track recording with map overlay

- TrackRepository + TrackPoint wired into MainViewModel:
  isRecording/trackPoints StateFlows, startTrack/stopTrack/addGpsPoint
- MapHandler.updateTrackLayer(): lazily initialises a red LineLayer
  and updates GeoJSON polyline from List<TrackPoint>
- fab_record_track FAB in activity_main.xml (top|end of bottom nav);
  icon toggles between ic_track_record and ic_close while recording
- MainActivity feeds every GPS fix into viewModel.addGpsPoint() and
  observes trackPoints to redraw the polyline in real time
- ic_track_record.xml vector drawable (red record dot)
- 8 TrackRepositoryTest tests all GREEN
