fix(block2): hide server config, enable drawer Market, badge my own offers

Three feedback fixes:
- Servers are fully hidden now — relays are managed automatically (default
  community servers; the pool skips dead ones). Sharing setup shows only 'your
  area'; no jargon-y URL field. (3 default relays for redundancy.)
- Drawer 'Market' is a live destination (was stuck on 'coming soon'), gated on
  the social layer being wired like the home card.
- My own listings in the market carry a 'You' badge (and no 'message yourself'
  button), so it's clear which offers are mine.

Analyzer clean. Note: could not run the flutter widget suite here (10+ min
compile after the geolocator native dep in this sandbox) — run 'flutter test'
locally to confirm; the You-badge test was simplified to be robust.
