fix(mutual/radar): bigger radar shortcut; no bounce-back on finished pass

- Pass card header: radar icon button enlarged to 48dp touch target with a
  24dp icon, spanning both header rows vertically (name/time + elevations);
  the pass info column narrows so the Opposite elevation shifts left.
- RadarDestination no longer auto-returns instantly when the mutual pass has
  already ended — the auto-return now only runs while the pass is actually in
  progress. Previously the collapsed-card radar shortcut appeared broken
  ('flash back to Mutual') whenever the computed pass had finished.
- Fakes: add the 4 last-sync bookkeeping members missed by the LoTW commit.
