Enatega Restaurant and Rider : No Buzzing Sound for Orders Until the Restaurant App is Opened

Is your feature request related to a problem? Please describe.

No order notification sound unless the restaurant app is opened. The restaurant app does not play a buzzing notification sound for new orders unless the app is actively opened. This behavior may result in delayed responses to incoming orders.
Ensure the app's notification system is configured to work in the background.
Implement push notifications or background services to trigger the buzzing sound immediately upon receiving a new order.
Verify that the app has the necessary permissions for notifications, including sound and background activity.
Prompt users to enable these permissions during onboarding or in the app settings.
Ensure that the buzzing sound is tied to the notification logic and not dependent on the app's active state.
Expected Behavior:
The app should play a buzzing sound for incoming orders regardless of whether it is open or running in the background.
