Allow Orders to Be Canceled and Refunded Before Being Marked as Paid

🔍 Problem Statement

Orders that have been created but not yet marked as paid cannot be cancelled or refunded. If an order was created in error or the customer changes their mind before payment, the admin has no way to void it — leaving orphaned order records.

💡 User Story

As a Pelcro admin, I want to cancel and refund orders before they are marked as paid, so that erroneous or unwanted orders can be voided cleanly without leaving orphaned records.

🎯 Definition of Done (DoD)

A feature is done when:

✔️ Given an unpaid order, when an admin cancels it, then the order status is set to cancelled, any associated pending invoice is voided, and no charge is processed.
