i18n: fix the final pre-merge review findings

Fixes the P1 and the confirmed P2 findings of the final review of the
i18n branch.

- CI: the air-quality model no longer imports i18n (portable module),
  so check:boundaries passes again.
- Air quality layer: named in the layer panel, HUD and voice; its
  Weather card, bands and errors translate. A test keeps the layer-name
  table in step with the layer registry.
- Layer statuses that still reached ru/es in English: GNSS, CelesTrak,
  Transit loading and feed errors, launches, perimeters, ALPR, ECCC,
  wind "field unavailable", Local ADS-B streaming lines.
- Voice and HUD: preset ids show city names ("Fly to San Francisco"),
  the HUD city translates, cockpit refusals cover frame, aircraft and
  satellite; empty Transit notes translate on the analyst card.
- tn() keeps a caller's formatted count ("12,345 map objects").
- Cyber HUD: the language button no longer covers the bottom-right
  card or the cockpit position readout.
- CCTV buttons wrap only in non-English locales; English layout matches
  main again.
- Switching language asks first when Provider Settings holds unsaved
  keys.
