* Configuración de tarjeta predeterminada durante la digitalización
* Se resolvió el problema por el cual la primera tarjeta digitalizada en la cartera D1 Pay no se establecía automáticamente como método de pago predeterminado. El flujo de digitalización actual establece automáticamente la primera tarjeta como predeterminada, eliminando la necesidad de llamar manualmente a `d1PayWallet.setDefaultPaymentDigitalCard()` API después de la digitalización.
