Subject: [PATCH] fix: listenAction must reply to prevent widget transport
 timeout

Previously the listenAction wrapper only called preventDefault() to stop
the switch default from firing an error, but it never sent a reply.
The widget transport would then wait for a response until it timed out.
Now the wrapper also calls transport.reply(ev.detail, {}) to return an
immediate success, fixing io.element.join, io.element.device_mute, and
set_always_on_screen.
