Fix to-device encryption info label (#3208)

* Fix to-device encryption info label
The label was shown also without checking that we use PerParticipantE2EE. Which is a prerequisite for toDevice transport. As a result the label was shown when not desired.

* rename: useLiveKit -> useLivekit

* make the settings naming consistent
