feat(backends): WebSocket-Toggle pro Backend

Browse Source 
Migration 0017 fügt backends.websocket BOOL. Wenn aktiv emittiert der
HAProxy-Renderer `timeout tunnel 1h` IM Backend-Block; defaults-Section
hat den Global-Timeout dafür verloren. Backends ohne WS-Workload bleiben
bei strikten HTTP-Timeouts (Connection-Hygiene). Migrations-Heuristik
schaltet vm-pool/proxmox/console/vnc-Namen auto auf true damit Proxmox-
Konsole nach Deploy weiterhin durchläuft.

UI: Switch im Backend-Modal + WS-Tag in der Übersichtstabelle.
