feat(controller): route status messages through notifications

- Send controller connected and disabled messages over a new IPC channel so they follow ankiConnect.behavior.notificationType
- Remove the separate controller status toast from the overlay
- Only announce connected controllers when controller.enabled is on
- Announce a controller again after it reconnects, and update usage docs
