Summary of Changes

Hello @Robert-SD, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces comprehensive support for the TWINT payment method across the platform. It integrates TWINT into both the Drop-in and Instant Component experiences, providing users with an additional, widely used payment option. The changes span across Android, iOS, and the Flutter/Dart layers, including updates to configuration, API definitions, and example app implementations to ensure seamless functionality.

Highlights

TWINT Payment Method Support: Full support for the TWINT payment method has been added, enabling its use within both the Drop-in UI and as a redirect Instant Component. This expands the available payment options for users.
Android Integration: The Android codebase has been updated to include the necessary configurations and component management for TWINT, ensuring it functions correctly within the existing payment flows.
iOS Integration: The iOS project now includes the AdyenTwint pod and related configurations, allowing TWINT to be processed on the iOS platform.
Flutter/Dart API Updates: New DTOs and configuration classes have been introduced in the Flutter/Dart layer to support TWINT, along with updates to the platform API and DTO mappers to facilitate communication between Flutter and native modules.
