FIX: correctly check for disabled notifications, tab and is idle (#27127)

This commit reuses the existing codepath in desktop-notifications and make it available to use to chat.

primaryTab was too hard to test if not impossible in this service test, however isIdle and disabled notifications are correctly tested.
