Enatega (Admin+Customer+Restaurant) : Reason for Order Cancellations feature

A clear and concise description of what you want to happen.

When the customer rejects the order, a pop-up should open and allow customer to write the reason for order cancellation OR display some common reasons of order cancellation from which user can select accordingly.

No files, tests, or entry points are named. Start by locating the customer order-rejection flow and the corresponding admin and restaurant order views; done means customers can provide a cancellation reason through free text or a defined list of common reasons, with the choice clarified before implementation.
