deviceIds are hashed per frame/origin, so the ids the menu got from the
chat page's enumerateDevices() were unknown inside the call iframe: the
fork fell back to the default output while the menu showed a tick on
the chosen device. Handle io.lotus.audio_output_state (also silencing
the fork's "host did not ack" log) and build the menu from the fork's
list and effective selection; older forks fall back to the old list.
