When ?rig_id= is specified on /audio, don't fall back to the global broadcast (which carries whichever rig is connected). Return 404 for rigs without an active audio connection instead of silently delivering the wrong rig's audio. Also create per-rig audio channels for all known rigs eagerly so connected rigs are instantly subscribable.
