The status WebSocket pool removed connections with list.remove(), which
raises ValueError on a double-remove (broadcast already dropped a dead
socket, then disconnect tries again), and only released a slot on
WebSocketDisconnect — any other error leaked the socket into the
broadcast pool. Centralise removal in an idempotent _drop() called from
a finally block and from _broadcast.

Adds optional live status checking per service (not just per node),
requested as a follow-up to issue #196.
Backend:
- New check_service / check_services: HTTP(S) GET for web services, TCP
connect otherwise; UDP and port-less non-web services stay 'unknown'.
- New scheduler job 'service_checks', independent interval (default 300s),
added/removed live via set_service_checks_enabled.
- Settings gain service_check_enabled + service_check_interval (>=30s),
persisted to scan_config.json. New WS message type 'service_status'.
Frontend:
- Live per-service status overlay in canvasStore (not persisted, so it
never round-trips through canvas save), fed by the WS message.
- DetailPanel + canvas node service rows: offline service turns red
(#f85149), otherwise keeps its category colour.
- SettingsModal: toggle + interval input (default 300s / 5 min).
Off by default — no behaviour change until enabled.

Token was visible in server logs, browser history, and proxy access logs.
Backend now accepts the connection first, then validates a JSON auth
message {"token": "<jwt>"} sent by the client on open before adding
the socket to the active connections pool.
C3 - config.yml contains credentials, remove from git tracking:
- Add backend/config.yml to .gitignore
- git rm --cached to untrack it
- Add backend/config.yml.example with instructions
C1 - SECRET_KEY must come from .env, no unsafe default:
- Remove hardcoded "change_me_in_production" default from config.py
- App now fails to start if SECRET_KEY is not set (pydantic required field)
- Generate real random key in backend/.env (gitignored)
- Add backend/.env.example for new contributors
H1 - WebSocket /ws/status was unauthenticated:
- Backend: require ?token= query param, validate via decode_token(),
close with code 1008 (Policy Violation) if missing or invalid
- Frontend: append ?token=<jwt> to WebSocket URL
Backend:
- asyncio.to_thread(_nmap_scan) — nmap no longer blocks the event loop
- Commit each discovered device immediately (previously one bulk commit at end)
- Update ScanRun.devices_found after each device so history panel shows live count
- broadcast_scan_update() pushes {type: scan_device_found} WS event per device
- Refactor broadcast_status to shared _broadcast() helper, adds type: "status" field
Frontend:
- useStatusPolling handles both WS message types (status / scan_device_found)
- canvasStore: scanEventTs + notifyScanDeviceFound() action
- PendingDevicesPanel auto-refreshes when WS scan event is received
