US: Handle Failed Orders and Send Payment Completion Links

[patrickhladun]

As a developer,
I want to add functionality to handle failed orders
so that when a purchase fails, the order is saved, and the customer can be emailed a link to complete the payment.

Objective

To improve the user experience by saving failed orders and allowing customers to complete payment later. Customers will receive an email with a link to complete the payment, and failed orders will be automatically removed after a set time.

Acceptance Criteria

• When a checkout form is submitted and the payment fails, the order is saved in the system as a "Failed Order."
• An email with a link to complete the payment for the failed order is automatically sent to the customer.
• The customer can click the email link and be redirected to a page to complete the payment.
• Failed orders are automatically removed from the system after a specified time.
• If the customer completes the payment within the time frame, the order status changes to "Completed."
