feat(heph-tui,hephd): surface sync health (last-sync age, conflicts, auth failure)
A spoke could be silently failing to sync (expired token → 401, or hub
unreachable) with the only signal buried in the daemon log. Now:
- hephd tracks SyncHealth (last attempt/success time, last error, auth-failure
flag) from the background sync loop and sync.now, classifying a 401 as an auth
failure. sync.status returns it plus the pending merge-conflict count.
- heph-tui shows a live status-line indicator (spoke only): '⟳ <age>' since the
last good sync, red '⚠ auth' when re-login is needed, '⚠ offline' when the hub
is unreachable, and '⚠ N conflicts' when conflicts are pending. The event loop
polls on a 2s tick so the age advances and failures appear while idle.
- docs: recommended Authentik access/refresh token validity to stop frequent
re-logins (with the iOS PWA localStorage-eviction caveat).
Closes the 'Add hub connection status to heph-tui' and 'Spoke sync health:
surface unhealthy state instead of silent 401 spam' backlog items.

heph-tui's status line now shows a live sync indicator for spokes: how long since the last successful sync (`⟳ 5m`), a red `⚠ auth` when the hub is rejecting the token (re-login needed), `⚠ offline` when the hub is unreachable, and a `⚠ N conflicts` chip when merge conflicts are pending. The daemon tracks this health and exposes it via `sync.status` (also visible in `heph sync --status`), so a silently-broken spoke is obvious at a glance instead of buried in the log.
