Delivered Button is not working Restaurant Application

Describe the bug
The "Delivered" button is not working in the Restaurant Application.

To Reproduce

Open the Restaurant Application.
Navigate to 'Processing' order tab.
Click the "Delivered" button.
Observed Behavior:
The button does not perform any action, and the order remains in the "Processing" or "Active" state.

Expected Behavior:
When the "Delivered" button is clicked:

The order should stop processing.
The order should be moved to the "Delivered" tab, indicating it is complete.
Proposed Solution:

Implement a trigger/action linked to the "Delivered" button that updates the order status to "Delivered."
Ensure the order is removed from the "Active" or "Processing" tab and displayed under the "Delivered" tab.
Provide visual confirmation or a success message to the user after the action is completed.

The issue names no files or tests. Run the Restaurant Application, open the Processing order tab, and trace the Delivered button's current behavior. Done means the order reaches the Delivered tab, leaves the Processing or Active view, and provides the described visual confirmation.
