release(v1.7.22-alpha): honest anchor status + Reconnect works on all nodes

- fips::service::active_unit() picks whichever fips unit is running
  (archipelago-fips.service vs upstream fips.service) so
  handle_fips_restart and handle_fips_reconnect don't silently no-op
  on hosts where the archipelago-managed unit was never created.
- peer_connectivity_summary(anchor_candidates) replaces the old
  identity-cache check. anchor_connected is now true when at least
  one authenticated peer's npub matches the public anchor OR any
  entry in seed-anchors.json, which matches what the user actually
  cares about ("am I in the mesh?") rather than what the card used
  to claim ("is this one specific public anchor reachable?").
- FipsStatus::query takes data_dir now (so it can read seed-anchors)
  rather than identity_dir. All call-sites updated.
- handle_fips_reconnect re-pushes seed anchors after restart so the
  new daemon gets dialed without waiting for the 5-min apply loop.
- FipsNetworkCard label drops "(fips.v0l.io)" — misleading now that
  multiple anchors may be configured.

-        Without the anchor, DHT routing to unknown npubs can't bootstrap; federation and messaging fall back to Tor until it reconnects. Reconnect restarts the FIPS daemon, which usually clears a stale identity cache.
+        No known anchor is currently an authenticated peer. DHT routing to unknown npubs can't bootstrap; federation and messaging fall back to Tor until one reconnects. Reconnect restarts the FIPS daemon, which usually clears a stale identity cache. Add a cluster-local anchor in Seed Anchors if the public one is unreachable.
