i18n: fix review findings and polish ru/es strings

Fixes the 51 P0–P2 findings from the full review of the i18n branch and
the issues found while checking every new string on screen in ru and es.

- Translate errors and statuses that still reached ru/es in English:
  feed and tile errors, provider statuses, the ALPR chip, the traffic
  mode chip, voice plan step labels, fire feed values, receiver bands,
  scene save reasons and the Cesium attribution link.
- Show preset city names in the UI language (src/ui/placeNames.js);
  data and everything sent to the model stay English.
- Share layer names between the layer panel, HUD and voice card
  (src/ui/layerNames.js).
- Keep long ru/es strings whole: voice card error lines, analyst
  titles, the voice tier status, the Nepal evidence button, the ALPR
  retry chip. English layout is unchanged.
- Ask before a language switch drops unsaved work.
- Catalog fixes: glossary terms (пуск, пресет), gender agreement and
  consistent "peticiones" in es, fewer calques in both languages.
- Fix English text that was itself wrong (e.g. "Exit cockpit to fly to
  a weather", raw tool ids in voice plan steps).

Catalogs: es/ru 2535 messages each, complete.
