[FEATURE] Support for auto-refund

### Feature Description

There are some cases in which the payment might not succeed initially and the customer drops out. Then the payment may succeed later and the customer is charged. A refund should be processed automatically in such cases.

### Possible Implementation

Some checks can be added and a refund can be triggered based on them in the `PaymentSync` flow.
