fix(i18n): toast, boot labels and AI tool text found in review

- The Space Missions cancellation failure toast read "[object Object]" in
  every language: the options object was passed as the message. The English
  message is the second argument again, the translation the third.
- Header text is translated before panel chrome builds its collapse labels,
  so the dock and display toggles no longer read "Expand VISUAL PRESETS" in
  another language.
- The voice "show data layers" result keeps the English layer name
  (row data-layer-name), not the translated row text.
- The Google 3D unavailable reason is translated in full.
