Crypto Refund Request Service

This service allows users to request a refund of cryptocurrencies when off-ramp orders have errors in their fiat transfer details (status: INVALID_WITHDRAWALS_DETAIL). The refund process is managed through multiple statuses and notifications via webhooks. Flows: 1. **Refund Request:** - Endpoint: `/orders/offramp/{orderId}/refund` - Description: Initiates a cryptocurrency refund request for orders with errors in their fiat transfer details. - Result: Generates a new order status `REFUND_STARTED` and sends a notification via webhook with the event `refund_started` to confirm the request receipt. 2. **Crypto Sending Process:** - Once the process of sending cryptocurrencies begins, the status changes to `REFUND_IN_PROGRESS`. A notification will be sent via webhook with the event `refund_in_progress`. 3. **Sending Confirmation:** - When the cryptocurrency sending is confirmed, the final order status will be `REFUND_DELIVERED` and a notification will be sent via webhook with the event `refund_delivered`. **Note:** - Multiple notifications may be received for each change in the order
