* Update ConfirmOrganizationUserCommand to use RequireTwoFactorPolicyRequirement to check for 2FA requirement
* Implement CanAcceptInvitation and CanBeConfirmed methods in RequireTwoFactorPolicyRequirement; update tests to reflect new logic for two-factor authentication policy handling.
* Refactor AcceptOrgUserCommand to enforce two-factor authentication policy based on feature flag; update validation logic and tests accordingly.
* Enhance ConfirmOrganizationUserCommand to validate two-factor authentication policy based on feature flag; refactor validation logic and update related tests for improved policy handling.
* Remove unused method and its dependencies from OrganizationService.
* Implement CanBeRestored method in RequireTwoFactorPolicyRequirement to determine user restoration eligibility based on two-factor authentication status; add corresponding unit tests for various scenarios.
* Update RestoreOrganizationUserCommand to use IPolicyRequirementQuery for two-factor authentication policies checks
* Remove redundant vNext tests
* Add TwoFactorPoliciesForActiveMemberships property to RequireTwoFactorPolicyRequirement and corresponding unit tests for policy retrieval based on user status
* Refactor UserService to integrate IPolicyRequirementQuery for two-factor authentication policy checks
* Add XML documentation for TwoFactorPoliciesForActiveMemberships property in RequireTwoFactorPolicyRequirement to clarify its purpose and return value.
* Add exception documentation for ValidateTwoFactorAuthenticationPolicyAsync method in ConfirmOrganizationUserCommand to clarify error handling for users without two-step login enabled.
* Update comments in AcceptOrgUserCommand and ConfirmOrganizationUserCommand to clarify handling of two-step login and 2FA policy checks.
* Add RequireTwoFactorPolicyRequirementFactory to PolicyServiceCollectionExtensions
* Refactor two-factor authentication policy checks in AcceptOrgUserCommand and ConfirmOrganizationUserCommand to streamline validation logic and improve clarity. Update RequireTwoFactorPolicyRequirement to provide a method for checking if two-factor authentication is required for an organization. Adjust related unit tests accordingly.
* Add PolicyRequirements namespace
* Update comments in AcceptOrgUserCommand and ConfirmOrganizationUserCommand to clarify two-factor authentication policy requirements and exception handling.
* Refactor RequireTwoFactorPolicyRequirement to return tuples of (OrganizationId, OrganizationUserId) for active memberships requiring two-factor authentication. Update UserService and related tests to reflect this change.
* Refactor AcceptOrgUserCommand: delegate feature flag check to the ValidateTwoFactorAuthenticationPolicyAsync method
* Skip policy check if two-step login is enabled for the user
* Refactor ConfirmOrganizationUserCommand to streamline two-factor authentication policy validation logic
* Refactor AcceptOrgUserCommand to simplify two-factor authentication check by removing intermediate variable
* Update documentation in RequireTwoFactorPolicyRequirement to clarify the purpose of the IsTwoFactorRequiredForOrganization
* Refactor AcceptOrgUserCommandTests to remove redundant two-factor authentication checks and simplify test setup
* Refactor AcceptOrgUserCommand and ConfirmOrganizationUserCommand to streamline two-factor authentication checks by removing redundant conditions and simplifying logic flow.
* Rename removeOrgUserTasks variable in UserService
* Refactor RestoreOrganizationUserCommand to simplify two-factor authentication compliance checks by consolidating logic into a new method, IsTwoFactorRequiredForOrganizationAsync.
* Remove outdated two-factor authentication validation documentation from AcceptOrgUserCommand
* Invert two-factor compliance check in RestoreOrganizationUserCommand to ensure correct validation of organization user policies.
* Refactor UserService to enhance two-factor compliance checks by optimizing organization retrieval and logging when no organizations require two-factor authentication.
* fix : split out the interface from the TwoFactorAuthenticationValidator into separate file.
* fix: replacing IUserService.TwoFactorEnabled with ITwoFactorEnabledQuery
* fix: combined logic for both bulk and single user look ups for TwoFactorIsEnabledQuery.
* fix: return two factor provider enabled on CanGenerate() method.
* tech debt: modfifying MFA providers to call the database less to validate if two factor is enabled.
* tech debt: removed unused service from AuthenticatorTokenProvider
* doc: added documentation to ITwoFactorProviderUsers
* doc: updated comments for TwoFactorIsEnabled impl
* test: fixing tests for ITwoFactorIsEnabledQuery
* test: updating tests to have correct DI and removing test for automatic email of TOTP.
* test: adding better test coverage
