Implement Payment Webhook

[italopessoa]

Create a webhook endpoint that receives payment confirmation from the provider (e.g., Mercado Pago).

• Use PaymentService to orchestrate calls to MercadoPago gateway and PaymentRepository
• Create GetPaymentStatus on MercadoPago gateway
• Add UpdatePaymentStatusUseCase
• Add UpdatePayment method to Payment repository
• Use existing UpdateOrderStatusUseCase to update order status if payment is approved

@italopessoa Here's the Mermaid sequence diagram for the webhook implementation process as described in the PR objectives. This diagram visualizes the interactions between the webhook endpoint, MercadoPago gateway, payment repository, and the order status update use case. Let me know if there are any adjustments or additional details you'd like to include!
