Overall Assessment: APPROVE

This PR removes the MANAGER value from the OrganizationType enum along with its mapping to OrganizationUserType.ADMIN in VaultSdkOrganizationExtensions, and updates the corresponding test fixture. The change is consistent with the PR description noting the server-side migration completed several years ago. A repository-wide search confirms no remaining references to OrganizationType.MANAGER in production or test code.
