feat(ui): say "Node busy" instead of "Launching dragonxd"; honest quit copy

A node rebuilding note witnesses for an hour was shown as "Starting
DragonX node... Launching dragonxd", which invited closing it.

- Overlay, a new NodeBusy banner and the status bar now say what the node
  is doing (rebuilding witnesses / catching up on blocks / up but not
  answering), with the elapsed time and Phase-1 block progress. A rebuild
  during startup warm-up replaces the stale "-28 Activating best chain"
  text, and the overlay re-applies its text once a second instead of only
  on a connect attempt (30s apart while the node is busy).
- Quit prompt: elapsed time, "Keep node running & quit" is the default,
  "Stop anyway & quit" becomes "Stop node & wait" (it no longer kills).
- A reinstall skipped because the node is still running now notifies.
- Status bar: don't repeat the warm-up status on the right, and don't
  print "Connected" there in non-English locales.
- i18n: 31 new keys in all 8 languages; 10 dead force-quit/old-modal keys
  removed; CJK subset rebuilt for the new glyphs.
- Tests: chooseDaemonStatus, NodeBusy banner priority, and every new key
  present in all 8 JSONs with matching printf conversions.
