feat(web5): anchor connectivity badge on FipsNetworkCard

Consumes the new authenticated_peer_count + anchor_connected fields
from fips.status. Shows a cyan dot + "connected" when fips.v0l.io is
in the identity cache (DHT routing to unknown npubs will work), or
an orange "not reached" with a one-line explainer that federation
and messaging will fall back to Tor until the anchor reconnects.

Peer count appears on the same row so users see "3 peers" when the
fleet-pair script has been run, or "0 peers" on a fresh install
still waiting for the anchor handshake.

Block only renders when service_active — pre-onboarding the FIPS
package is masked so there's nothing meaningful to report.

Covers the UI half of task #20. Multi-anchor defaulting is still
open (need real anchor addresses beyond fips.v0l.io).
