Add isDisabledInternally to SubscriptionModel for IV logout

When Identity Verification is ON and logout is called, the SDK now
sets isDisabledInternally=true instead of optedIn=false. This
preserves the real opt-in preference while telling the backend the
subscription is disabled. On the next login, UserSwitcher creates
a fresh SubscriptionModel that defaults isDisabledInternally=false,
restoring the real state automatically.
