Release - 4.7.0 (#330)

This release adds support for new sdk clients: Agentic Commerce, Compliance Requests and GooglePay. It introduces new API clients, request/response entity classes, and updates the main `CheckoutApi` class to expose these clients. Additionally, it updates the API client to allow passing custom headers for POST requests. These changes enable delegated payment token creation, compliance request retrieval, and response submission.

**Agentic Commerce API integration:**

* Added `AgenticCommerceClient` for creating delegated payment tokens, including support for custom integrity headers and idempotency keys.
* Introduced related entity classes: `DelegatedPaymentRequest`, `DelegatedPaymentAllowance`, `DelegatedPaymentBillingAddress`, `DelegatedPaymentMethodCard`, `DelegatedPaymentRiskSignal`, and supporting enums/types for card and funding types.
