[PM-21179] Add interface to check if user is enrolled in account recovery (#6993)

* Add validation for reset password key and account recovery enrollment in OrganizationUser

* Update admin approval logic to check account recovery enrollment and add tests for reset password key validation

* Enhance UserService validation to include account recovery enrollment and add unit test for empty or whitespace reset password key handling

* Refactor OrganizationUserUserDetailsQuery to validate reset password keys and add unit tests for filtering out invalid keys

* Update AdminRecoverAccountCommand to validate account recovery enrollment and adjust tests for whitespace reset password keys

* Enhance OrganizationUserRotationValidator to validate reset password keys, including filtering out whitespace-only keys, and add corresponding unit tests for validation logic.

* Refactor OrganizationUserUserDetailsQueryTests to remove unnecessary whitespace-only test cases for account recovery key validation.

* Refactor MemberResponseModel to use OrganizationUser's validation method for ResetPasswordEnrolled status and update corresponding unit test for clarity.

* Refactor OrganizationUsersController and response models to utilize OrganizationUser's validation method for ResetPasswordKey, ensuring consistent validation across the application. Add unit tests for OrganizationUser to verify key validation logic.

* Update OrganizationUserRotationValidator to handle null reset password keys and adjust tests for client-side bug. Add comments for future migration after resolving PM-31001.

* Fix whitespace issue in UserServiceTests.cs by removing BOM character from the file header.
