Description

This PR improves the device error handling on the Device Selection Screen. It fixes an issue where the microphone was not acquired when the camera permissions were disabled.

Now the user can explicitly deny just their camera or microphone permissions and the app will function as expected. The app will display warnings to the user if they have denied any device permissions.

Resolves #428
