fix(i18n): Google controls, vessel units and counts follow the UI language

Screens that only open with provider keys showed a few gaps:

- Google Street View's own controls (Map Data, Terms, Report a problem)
  and its addresses were always English: the Maps script now loads with
  the UI language. English adds no parameter, as before.
- The selected-vessel HUD line kept KT and DEG after translated labels.
- Layer counts used a decimal point (12.0K); other languages use their
  own separator (12,0K).
- A collapsed rail title was cut with an ellipsis in Russian; tighter
  tracking fits it whole. English is unchanged.
