🛂(backend) allow participants to mute others based on room configuration

Enable any participant to mute others when the room configuration
allows it. This is enabled by default for all meetings unless
explicitly disabled by an administrator.

Privileged users retain the ability to mute any participant
regardless of the room configuration.
