Code Review

This pull request removes the legacy 3DS2 "classic" flow, deleting ThreeDS2ClassicActionHandler and consolidating 3DS2 actions. Feedback identifies a potential regression where paymentData is no longer propagated in 3DS2 actions, resulting in nil values in integration tests. Additionally, suggestions were made to use package visibility for ThreeDSResult and the Error enum to maintain consistency with the AuthenticationComponent and facilitate cross-module access.
