fix(i18n): restore English output changed by the i18n foundation

A side-by-side English comparison with main found text the branch changed:
- Layer list names: #601 let its own catalog names win over the panel's
  English names, so "Live Vessels" read "Live AIS Vessels", "Bike Share"
  "Bikeshare", "Cameras" "CCTV", "Data Centers" "Datacenters", "Active Fires"
  "FIRMS Active Fires". The panel names win again.
- HUD feed-state suffix is "UNAVAILABLE LIVE AIS VESSELS" again (Russian keeps
  its colon); the mission panel aria-label is "Selected Space Mission" again;
  scene shot timing is "4.0s + 0.9s" again.
