feat(settings,map,docs): polish Relays UI, drop desktop Near Me, remove NoGood Radio
- Settings -> Relays: rewritten with sectioned cards (NIP-65 / DM inbox / Local /
Blocked), inline clickable Read/Write chips (no more Edit popover), tone-coded
sections with icons + counts + help text, cleaner add rows and empty state.
- Map: removed the desktop 'Near Me' button (mobile floating control remains).
- Removed NoGood Radio everywhere: deleted NOGOOD_RADIO_PROPOSAL.md and
RADIO_PLAYER_GUIDE.md, dropped the README feature line, scrubbed 'DJ NoGood'
examples from LIVE_MUSIC_PROPOSAL.md.
Gate: 101 tests, 0 errors/warnings, boot smoke green.
