Restaurants with High Delivery Charges Should Not Be Displayed Outside Delivery Area

Describe the bug
Some restaurants (e.g., Farm Fresh - Wadi Halfa) in the Enatega app have very high delivery charges due to their location being far from the user's delivery address. These restaurants should not be displayed if they lie outside the delivery premises or serviceable area.

To Reproduce

Open the Enatega app.
Set a delivery address that is far from certain restaurants (e.g., Delish Bites Co.).
Browse through the list of available restaurants.
Observe that some restaurants with high delivery charges are still displayed in the search results.
Expected behavior

Restaurants that fall outside the delivery service area or have prohibitively high delivery fees due to distance should not be displayed in the list of available restaurants.

Actual Behaviour
Restaurants that are located far from the delivery address are still displayed, despite the high delivery fee.

The issue names no files, tests, or implementation entry points. Start by tracing how the Enatega app builds the available-restaurant search results for a selected delivery address, then identify how serviceable areas and delivery charges are determined. Done means restaurants outside the service area or an agreed distance or fee limit are excluded, with coverage for the reported examples.
