Riders are not receiving orders within their designated zones.

Summary:
I created a specific zone, registered a rider within that zone. However, when I places an order, the rider is not receiving any orders, even though they are both located in the same zone. This process is not functioning seamlessly as expected.

Expected Behavior:
The riders should receive an order when a user places an order.

Current Behavior:
Riders should be receiving orders within their designated zones.

How it occur:
I established a zone, subsequently adding a rider, and then assigned that specific zone to the rider.
Orders are being received within the restaurant app but are not appearing in the rider app.

Reproduce the described flow by creating a zone, assigning a rider to it, and placing an order. Trace the order from the restaurant app into the rider app, focusing on the zone-assignment and rider-notification entry points. Done means an eligible rider in the same zone receives the order in the rider app; no files or tests are identified in the issue.
