Add camera-manager service and Video-page camera selection#98

Adds a camera-manager FastAPI microservice (port 3005, proxied at /api/camera) that enumerates connected V4L2 capture devices — classifying CSI vs USB the same way the rtsp-server does — and selects which one the RTSP server streams by writing [camera].device into rtsp-server.toml and restarting the unit. The Video page gains a camera picker (shown only when more than one camera is connected) that lists detected cameras and switches the active source via the new API, then reconnects the WebRTC stream once the server restarts. Wires the service through assemble_tree.sh, the postinst enable list, the ark-ui-backend proxy, and the mypy contract set; seeds device = "" in the packaged rtsp-server.toml. Bumps the rtsp-server submodule to the commit that adds the matching USB-camera pipeline support.

Summary
Lets you pick which camera the RTSP server streams from the web UI, the companion to USB-camera support in ARK-Electronics/rtsp-server#13.
Following the existing
*-managerpattern (each service exposes its own API + page; the TOML config is persistence, not a data channel), this adds a dedicated camera API and a picker on the Video page.camera-manager service
A new FastAPI microservice (port 3005, proxied at
/api/camera):GET /cameras— enumerates connected V4L2 capture devices viaVIDIOC_QUERYCAP, classifying CSI vs USB the same way the rtsp-server does (UVC metadata-only nodes filtered out), and flags the one currently being streamed.POST /select— writes[camera].deviceintortsp-server.tomland restartsrtsp-server.service(uses the existing service-user polkit grant, which already listsrtsp-server.service).Video page
A camera dropdown that appears only when more than one camera is connected. It lists each camera (CSI/USB + device path), switches the active source through the API, and reconnects the WebRTC stream once the server restarts. If the camera-manager is unreachable, the picker stays hidden and playback is unaffected.
