feat: androidtv navigation, auto-tunneling pause

Improved AndroidTV navigation to be less clunky and more streamlined

Added auto-tunneling pause feature to UI to allow of quick auto tunneling pauses.
App shortcuts and quick tile also override auto tunneling by engaging pause for temporary override of VPN purposes.

Fixed bug where auto start on reboot was not working on older devices and AndroidTV.

Fixed bug where location services is prefenting some flavors of Android from using auto-tunneling.

Fixed bug where location permissions were not being detected correctly on AndroidTV versions.

Fixed bug where quick tile could become out of sync.

Improved notifications to show proper state of auto-tunneling and vpn.

Removed excessive vibration from notifications.

Improved error handling.

Closes #75
