The CI "build" job failed with CS0246: IGrandAuthenticationService could not be found in LoginControllerTwoFactorTests.cs. The test had drifted from the current LoginController API. Fixing the missing import exposed two further constructor-signature mismatches and a runtime failure in one test.

• Imports
  • Added Grand.Web.Common.Security.Authentication, which is where IGrandAuthenticationService lives.
  • Added Grand.Web.Common.Localization for IRequestTranslationService.
• Constructor mocks
  • ITranslationService is now IRequestTranslationService.
  • IMessageProviderService is now ICustomerMessageProviderService.
  • These match the LoginController constructor and the sibling LoginControllerExternalSignInTests.
• Context accessor
  • SecondStep_ValidCode_SignsInToThePanel threw a NullReferenceException in BaseLoginController.SignInAction.
  • That method reads WorkContext.CurrentCustomer, StoreContext.CurrentStore and WorkingLanguage from the accessor.
  • The IContextAccessor mock is now created with DefaultValue = DefaultValue.Mock, as the sibling test does.

new Mock<IContextAccessor> { DefaultValue = DefaultValue.Mock }.Object

Only the test file changed; no production code is touched.
