fix(flights): address review — quotable squawk only, all military tint sites, no test churn

- aircraftEmergency: `source` is 'squawk' only when the Mode A code itself
  names the status; the Cockpit HUD no longer quotes an unrelated squawk
  (e.g. SQUAWK 1200 on an ADS-B `downed` status).
- military: new billboards and the untrack restore use the fleet tint, so an
  emergency stays red instead of snapping back to amber; tint helpers take the
  record already in hand instead of a second lookup.
- cockpit/cyber CSS: emergency colour via a custom property / theme token,
  meta line bolded so the status does not rely on colour alone in the HUD.
- tests: revert Prettier churn in unscoped test files; only semantic edits.
- docs/CURRENT-STATE.md: transponder emergency highlighting section.
- qa-emergency-squawk: (iv) RELEASE check; new files added to format scope.
