Adds a new payment module for Klarna, enabling Klarna Payments integration. Key features implemented: - Basic module structure (`Smartstore.Klarna`) including `module.json`. - Klarna API client (`KlarnaHttpClient`) for communicating with the Klarna Payments API (sessions, orders, tokens). Includes request/response models and error handling. - Klarna payment provider (`KlarnaPaymentProvider`) implementing `IPaymentMethod` with logic for processing payments (session creation) and placeholders for capture, refund, and void operations. - Configuration settings (`KlarnaSettings`) for API credentials and environment, with an admin UI for management (supporting multi-store overrides). - UI components (`KlarnaPaymentViewComponent`) and views for rendering Klarna elements in the checkout process (placeholder for Klarna JS SDK integration). - Admin and public controllers (`KlarnaAdminController`, `KlarnaController`) for settings management and handling Klarna callbacks/notifications (placeholders for full implementation). - Localization resources for English and German. - Initial unit tests for the API client and payment provider, establishing the testing structure. Further work will be required to fully implement the client-side JavaScript SDK integration, complete the payment processing logic in the provider (capture, refund, void), and thoroughly test the end-to-end payment flow.
