Require authorization before turning off eSIM security feature

eSIM has a feature that requires an auth check before deletion, this
adds a security check before allowing the security feature to be turned
off.

TogglePreferenceController was changed to BasePreferenceController to
separate updating the state from UI press and updating from code.
