fix(i18n): keep values the AI tools read in English

- Satellite class in analyst records and voice payloads stays English
  ("STATION", "COMMS"), so voice filters on the class work in every
  language; cards and the legend still show the translated label.
- Layer source names (OSM routing, ALPR sources) stay English in layer
  state; the layer row translates them.
- New translateKnown(): catalog text when there is an entry, the given text
  otherwise, with no warning. The layer row uses it for loading labels and
  errors, Recent Imagery for its notices.
- Mark the remaining Recent Imagery and wind messages.
