Entities:
- New entities table — id, name, type (camera|html|web), camera_id,
html_content, web_url
- Auto-create entity per camera on createCamera
- Layout cells reference entity_id (replaces inline content_type/
camera_id/html_content/web_url)
- Bundle resolves entities back to legacy cell fields for kiosk compat
(Rust kiosk unchanged)
- Full CRUD: /admin/entities, /admin/entities/new, /admin/entities/:id
- Cell editor: single entity dropdown with type badges
ONVIF discovery:
- /admin/cameras/discover — host/port/user/pass form
- Server queries ONVIF device, lists profiles with name/resolution/
encoding/framerate
- "Add" creates camera + main stream from chosen profile
- shared/onvif.ts: minimal SOAP+UsernameToken+PasswordDigest client
(no external dep)
- Camera new form simplified to RTSP-only with discover link
Server side:
- service-coordinator-ws: full WS implementation using ws package
- Auth via ?token=<kiosk_key> query param
- Coordinator registry for cross-plugin notification
- Admin mutations call notifyKiosks() → server pushes reload-bundle
- 30s ping/pong heartbeat
Kiosk side:
- Rust ws_client with tokio runtime + tokio-tungstenite
- Auto-reconnect with exponential backoff (1s → 60s cap)
- On reload-bundle: re-fetches bundle, re-renders layout
- Pong replies to server pings
Also fix: auto-suffix kiosk name on UNIQUE collision (re-pair with
same hostname no longer fails).
