Merge main: preserve embedded track detail map, tack detection fixes, 0.12 past track opacity

- Tack detector: STABILITY_MAX=30, START_SKIP_MS=120s cold-start filter (feature branch)
- TrackDetailSheet: embedded Fragment with MapView, back button pops stack (feature branch)
- layout_track_detail_sheet: MapView top half, detail panel bottom half (feature branch)
- MapHandler past track dim opacity: 0.12 (down from 0.22)
- SavedTracksFragment: fragment transaction to TrackDetailSheet + SAF setup (both)
- VoiceLogFragment: inline track list, logViewModel refs fixed (main)
