maziggy 62a64006b8 fix(camera): stop /camera/stop from letting a second socket open (#2521)
The single-connection barrier from the last round was correct and was being
bypassed. shutdown_broadcaster() popped the broadcaster out of the registry
and only then awaited its teardown, so while the socket was still closing the
slot sat empty: a /camera/stream request landing in that window minted a
broadcaster with no predecessor and dialled port 6000 immediately. A page
reload fires /camera/stop and the new stream request concurrently, so a P1S
ended up holding two connections, kept feeding the orphan, and starved the
live viewer until its TCP keepalive reaped the dead one ~20 min later. The
stopped broadcaster now stays in the registry so the successor chains behind
its socket close.

The camera page also rendered the <img> src before the stream token arrived
whenever auth was disabled, then swapped it once the token landed — aborting
the in-flight request and issuing a second one. With auth off both reached the
backend, so every load attached two viewers to a one-socket printer. The src
now waits for the token query to settle.

Subscribers only checked for client disconnect after yielding a frame or on a
30s idle timeout, so a viewer that left during a black stream stayed counted —
and /camera/stop trusts that count to decide whether to tear the upstream down.
