- Generic WebSockets (stats, exec) now connect to /ws?nodeId= instead of
the bare root so the upgrade handler detects the remote node and proxies
the WS connection to the correct remote Sencho instance.
- Vite dev proxy gains ws:true on /api and a new /ws entry so WebSocket
upgrades reach localhost:3000 during npm run dev.
- Backend WS message handler falls back to the default local node when the
nodeId in a proxied message doesn't exist in the local DB.
- Open App button now extracts the hostname from the remote node's api_url
instead of using window.location.hostname.
