feat: 2.0.0-alpha.11 — DB-backed service registry + LAN auto-discovery

- monitored_services table (mig 015) replaces config/services.json (now a boot seed)
- owner CRUD over /api/health/services; GET is DB-backed; cron+worker read the DB
- discover.lan worker: pure-Node TCP sweep + HTTP-title probe -> disabled 'discovered'
  candidates (never clobbers curated entries); POST /api/health/discover + GET .../discovered
- dashboard: Scan button + Discovered(N) section with one-click promote
