fix: discount store DeliveryStatus stays Pending after payment (matches regular store)

- CompleteOrderPaymentCommandHandler: DeliveryStatus.InTransit → DeliveryStatus.Pending
- PlaceOrderCommandHandler (full discount-balance path): same fix
- Now both stores behave the same: admin must manually update delivery status
- Consistent with regular store flow where order stays Pending after payment
