Code Review

This pull request updates the Adyen Checkout API Java SDK models. It introduces new model classes for CheckoutForwardAccountUpdateResult, CheckoutForwardNetworkTokenResult, OpiRequest, and OpiResponse. It also adds support for the Satispay payment method, introduces the payable field to checkout session requests and responses, adds klarnaNetworkPaymentAccountId to Klarna network details, and includes riskCategory in line items. Furthermore, OPI request and response fields have been integrated across multiple payment and stored payment method models, alongside various Javadoc updates. There are no review comments to assess, and I have no additional feedback to provide.
