feat(ios): add Live Activity connection status + stale cleanup (#33591)

* feat(ios): add live activity connection status and cleanup

Add lock-screen/Dynamic Island connection health states and prune duplicate/stale activities before reuse. This intentionally excludes AI/title generation and heavier UX rewrites from #27488.
