[API] New Card Transaction Type refund_reversal

Added refund_reversal (Refund Reversal) to the Card Transaction Type enum, with the corresponding account-side type card_refund_reversal. When the channel reverses a previously credited refund, the system generates refund_reversal and debits the over-refunded amount from the customer side. The fund direction is a debit, which is the opposite of refund.

[API] Related Fields

• preTransactionId / preOrderNum point to the original refund order, not the original consumption order.
• The notes field may contain Refund reversal, related refund order No.: {orderNum}.

[Guides] Integration Note

The new refund_reversal type may appear in card transaction lists, transaction details, and Webhooks. If your integration uses a whitelist or switch on type, add refund_reversal to avoid parse failures or missed handling.
