你的任務是在用戶的專案中實作 KryptoGO Payment Webhook 回調處理。
詢問用戶：
框架類型：你使用什麼後端框架？
資料庫：使用什麼資料庫儲存訂單？
用戶輸入: $ARGUMENTS
建立 POST 端點接收 KryptoGO 的回調通知。
端點路徑建議: /api/payment/callback 或 /webhook/kryptogo
必要行為:
payment_intent_id 存在於資料庫status 更新訂單狀態必須處理以下 5 種狀態：
| 狀態 | 處理邏輯 |
|---|---|
pending | 通常不會收到此狀態的回調 |
success | 更新訂單為已付款，記錄 payment_tx_hash |
expired | 標記訂單為過期 |
insufficient_not_refunded | 記錄異常，等待退款 |
insufficient_refunded | 記錄退款資訊 refund_tx_hash、refund_amount |
確保同一個 payment_intent_id 的回調不會被重複處理：
