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.

Verified first: the embed hides Element Call's footer, so its in-call
settings sheet (which has the output picker) is unreachable from Lotus;
the cinny call bar had no output control.
Now a speaker button next to Deafen (desktop bar only; hidden where
setSinkId is unavailable — Firefox, Safari, Android Chrome) opens a menu
of enumerateDevices() audio outputs with the current one checked; picking
one sends io.lotus.set_audio_output to the fork (≥ 0.25.0-lotus.11),
which selects it, and the choice is re-sent with the rest of the sticky
fork state after an EC remount.
