feat: node workflow redesign — wizard auto-config, reset, MusicBrainz contact

Wizard (Electron):
- Auto-provisions node config (hub URL + username) from logged-in user
- node:start handles both cold start and restart of misconfigured daemon
- Waits for daemon to reach 'running', auto-links node key on hub
- probeNode accepts intermediate states for wizard progress feedback

Reset (meshbay-node reset):
- Unlinks node key from hub (DELETE /me/node_key, best-effort)
- Stops and disables daemon (systemctl --user disable --now)
- Erases ~/.config/meshbay, ~/.local/share/meshbay, ~/.local/state/meshbay

MusicBrainz contact:
- Resolved from owner's hub email instead of per-node roster config
- Removed musicbrainz_contact UI and WebRTC handshake field
- Removed set_musicbrainz_contact/musicbrainz_contact from roster

Node pairing:
- Added operator pairing banner on NodePage
- Added operator_paired flag to list_groups
