⏪️(frontend) revert old permission-toggle hotfix

Revert the old hotfix that allowed users to toggle their microphone
or camera while permissions were not granted, which then triggered
a `getUserMedia` call to prompt for them.

Now that the permission store is properly kept in sync with the
browser, this workaround is no longer needed as-is. The intended
behavior will be reimplemented cleanly in a later commit.
