### Document payin refund status

* [Query payin](https://docs.pay247.io/api-reference/en/payin_query.md#refund-status): clarify that `data.status = REFUND` means refunded, and add a status explanation and query response example.
* [Payin notification](https://docs.pay247.io/api-reference/en/payin_notify.md#refund-status): add `REFUND` (refunded) to the documented `status` values, provide a refund notification example, and explain refund status changes after payment success and idempotent handling of duplicate notifications.
* Refund status uses the existing `status` field, with no new request parameters or response fields. `amount` and `fee` still represent the original order amount and order fee; neither represents the actual refund amount.
* Add this page and its navigation entry. Future API documentation changes will be listed in reverse chronological order.
