registerTokenForPushNotification static method

Future<void> registerTokenForPushNotification(String token, { required dynamic onSuccess(String response)?, required dynamic onError(CometChatException excep)?, })

Registers the obtained FCM Token which will be used by the CometChat server to send message via push notification.

method could throw PlatformException with error codes specifying the cause Registers a device token for push notifications.

Migration Note: Migrated from platform channels to native Dart implementation. Uses PushRepository for token registration. Behavior and signature remain identical for backward compatibility.
