fix: register session with addSession() to activate Media3 notifications

MediaSessionService only sets up its internal MediaNotificationManager
when addSession() is called. This normally happens when a MediaController
binds, but since we use custom intents, no controller ever connected.
Calling addSession() after session creation activates the notification
pipeline. Also removed debug logging.
