Fix CI: update stale geo-block assertion; drop unused favorite string

- CommandProcessorTests still asserted the old "blocked … in geohash
  chats" copy that this branch rewrote to the per-channel wording.
- The `mesh_peers.state.favorite` state constant was replaced by the
  mutual/pending pair and left unused — Periphery (now blocking) flagged
  it. Removed.
