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.
