This is same-session only. We still don't store any session data or
cookies. We dump mute and volume settings to an object when a webcall
stream is reaped, then restore them if the stream comes back.
This should address hardship in a lossy connection or someone
"quickly restarting OBS" needing to re-unmute the player.

10,000 hours mucking with `git filter-repo` and no reasonable use-case
found. On the plus side, anyone looking at this and curious what I nuked
isn't missing much. This lived in a monorepo up until about a week ago.
