Move Saved Tracks to Log tab; restore conditions sheet on back

- hideOverlays() now resets bottomSheetBehavior to COLLAPSED/not-hideable,
  so the conditions sheet reappears correctly when returning from any overlay
  (previously it stayed hidden after navigating away via the track browser)
- Remove btn_saved_tracks from the conditions sheet (layout + click handler)
- Add btn_saved_tracks to the Log screen layout and wire it in VoiceLogFragment
  via MainActivity.showSavedTracks(); tracks live with the log, not with weather
