Handle export of zero cost transactions #681
Description
Accounting export of month 2025-10 failed:
Transactions and completed payments do not match, [(Transaction(id=20295, amount=0.00, status=Status.completed, created_at=2025-10-22 19:41:41), None), (Transaction(id=20296, amount=0.00, status=Status.completed, created_at=2025-10-22 19:42:13), None)]
I believe the cause of this to be that both of the listed transactions are sales of an item with the cost set to zero at the time of purchase. Which means there's no corresponding payment in Stripe for obvious reasons.

A related thing to check is whether this also affects orders that have a zero cost due to a discount, for example the discount code used for subsidized material used in when holding courses.
