Reject cross-origin websocket connections (#24714)
* reject cross-origin websocket handshakes

Neither /ws nor the jsmpeg websockets checked Origin, and the internal port grants admin to everyone, so any page a LAN user visited could open ws://frigate:5000/ws and send commands or read streams. Both servers now reject a browser handshake whose Origin host matches neither Host nor X-Forwarded-Host, and allow handshakes without an Origin for non-browser clients. nginx now forwards an outer proxy's X-Forwarded-Host instead of overwriting it, so proxies that rewrite Host and the Home Assistant integration's proxy still match.

* apply runtime role changes to jsmpeg streams

The output process never subscribed to config/auth, so role edits from the Roles UI (requires_restart 0) did not reach it and jsmpeg kept streaming cameras that had been removed from a role until restart. The output process now replaces its auth config on config/auth updates, which the camera and birdseye broadcast threads read through the shared config.

* tidy origin check docstring and auth update comment

* reject cross-origin go2rtc stream requests in /auth

The go2rtc websockets and the webrtc offer POST still accepted any Origin, since go2rtc runs with origin "*" and /auth grants admin on the internal port, so a page on another site could pull live video through a LAN user's browser. nginx now passes Origin, Host, X-Forwarded-Host and Upgrade to /auth, which rejects a websocket upgrade or go2rtc stream request with a foreign Origin before the internal-port early return. The hostname rule moves to frigate/util/origin.py so /auth and the ws4py servers share it.

* set Host in the nginx proxy doc examples

* drain all queued auth updates in the output process

* note that cards must stream through the integration proxy

* strip the query before matching go2rtc paths in the origin check
