fix(i18n): fix Russian layouts and the gaps the screenshot review found

A review of the Russian UI screenshots found ~90 places where longer words
broke the layout or text was still English. Fixed so they hold for any
language, then shortened where a control is short by design.

- Layout: label columns that size to their text (weather and wind settings,
  Recent Imagery slots and opacity, style sliders, display panel), layer
  list names and icons, buttons that wrap instead of overflowing (CCTV,
  scenes, Bhote Koshi), voice header that always shows the cost, styled
  EN | ES | RU chips, voice error tray above the dock.
- t() context: t('CLEAR', { context: 'action' }) is «СБРОСИТЬ» while the sky
  stays «ЯСНО»; also used for radio categories, voice states and directions.
- Units and dates follow the locale through src/ui/unitLabels.js
  (formatQuantity: localized number, translated unit, non-breaking space):
  wind, pressure, cyclones, directions, CCTV, SDR gain, scene timing, flight
  tooltip, Recent Imagery dates and resolution.
- Newly translated: directions turn-by-turn steps (built from the maneuver;
  English matches the server word for word), HUD mode and summary, voice
  card states, radio categories on the globe, CCTV status, layer source
  lines, scene dialogs (Cancel, file pickers), Bhote Koshi statuses, titles,
  comparison dates and caveat, Recent Imagery notices. Stored data and text
  for AI tools stay English.
- es and ru: 1,885 messages each.
