Get one frame from an active HTTP MJPEG source

GET 
/stream/http/src:index.jpg

Waits for and returns a single JPEG frame from an active HTTP MJPEG source. This is useful for thumbnails, readiness checks, and test assertions without maintaining a streaming connection. A stopped or non-HTTP source returns a conflict, and a frame acquisition timeout returns 504.
