Unable to Edit Order During Checkout on Customer Web

[MahnoorNaseer]

Description:
Customers are currently unable to edit their orders when they reach the checkout page on the Enatega customer web platform. This limitation hinders the user experience, as it prevents customers from making last-minute changes to their orders without having to start the process all over again.

Steps to Reproduce:
1- Navigate to the Enatega customer web platform.
2- Add items to the cart.
3- Proceed to the checkout page.
4- Attempt to edit the order (e.g., change item quantity, remove an item, or add a new item).

Expected Result:
Customers should be able to edit their orders directly from the checkout page without needing to go back to the previous steps.

Actual Result:
Customers cannot make any changes to their orders once they reach the checkout page. Any changes require navigating back to the cart or starting a new order.

Impact:
This issue impacts the overall user experience by adding unnecessary steps and potentially causing frustration for customers who wish to make last-minute adjustments to their orders.

Priority:
High - Enhancing the checkout experience can significantly improve customer satisfaction and reduce cart abandonment rates.

Proposed Solution:
Implement functionality that allows customers to modify their orders directly from the checkout page. This may include:
1- Editing item quantities
2- Adding or removing items
3- Applying promo codes or discounts
