Sort track history chronologically; add Report button to track list

- getSavedTracks() now returns tracks sorted by startMs ascending so
  the overview list shows oldest→newest
- item_saved_track.xml gets a small REPORT text button below the stats row
- SavedTrackAdapter wires onReport callback; SavedTracksFragment navigates
  to TripReportFragment.newInstanceForSavedTrack() after selecting the track
- TripReportViewModel.generateReportForSavedTrack(track) generates a
  post-trip narrative from a completed SavedTrack's points + logbook entries
- TripReportFragment detects ARG_FOR_SAVED_TRACK, reads selectedTrack from
  MainViewModel, and uses the saved-track variant; Refresh button re-runs
  the same variant
