Pull Request Overview

This PR implements a 2-phase refund flow that separates the immediate refund processing from the payment gateway communication. The refund process now creates a refund request immediately and then queues a job to handle the actual payment gateway refund processing asynchronously.

Key changes:

• Split refund processing into immediate database operations and asynchronous payment gateway processing
• Added new job ProcessPaymentGatewayRefundJob for handling payment gateway refunds
• Added repository dependency for refund request management
