feat(ui): mesh Refresh/Broadcast feedback, Set Recommended modal with probe progress bar, live list refresh

- Refresh button: real handler — calls the new mesh.refresh (radio
  re-query) plus contacts/federation/outbox re-reads, disabled with a
  spinner while running (was an unawaited cache repaint with no feedback
  that skipped half the list's data sources).
- Broadcast button: success ('Sent ✓') and failure states with the error
  in the tooltip; failures no longer vanish as unhandled rejections.
- The store's 5s status poll no longer wipes the error banner each tick.
- Contacts/aliases, federation nodes and the outbox badge refresh every
  ~30s (were mount-only and went permanently stale).
- Peer-list empty state keys on the merged list, so federation rows and
  the channel rows still render with no radio attached.
- Device setup modal: 'Set Recommended' naming, probe progress bar with
  stage labels instead of an anonymous spinner.
- Device panel: name save clears properly (empty = fall back to server
  name) and the confirmation reflects the new live apply.
