i18n: fix the repeat-review findings

- Status pieces translate in one place (src/ui/statusText.js): a Local
  ADS-B error with a single piece now translates, and the analyst card
  splits empty-layer notes into pieces (Transit, Local ADS-B).
- Translate the ALPR retry chip text, the ECCC error on the Air quality
  card, "Upstream response too large" and the "entry {n}" feed label.
- The unmarked-text check also sees error/loadingLabel/statusMessage/
  status assignments, `status:` properties and showToast?.( /
  this._showToast( calls; the scene import preview marks its pack
  statuses, data and model-facing text carry i18n-ignore with a reason.
- Tests check the real code: the HUD locality formatter moves to
  src/hudLocalityFormat.js, the unsaved-keys test pins the teardown.
- One copy each: city names come from src/cityPois.js, the GNSS HTTP
  template and wind "field unavailable" texts; dead fallbacks removed.
- Leftovers of the reverted vessel-label change and the reformatting of
  detectionHost.test.mjs / keySetup.test.mjs are back to main.

 Fix it by marking the text. When the text must stay as it is, say so where it lives:
