📔 Objective

This is to allow for the auto enabling of the Single Org Policy when a claimed domain is verified. This will also block a user from disabling the Single Org Policy if the organization has any verified domains.

This also included a refatctor of the ValidateOrganizationDomain scheduled job to use the VerifyOrganizationDomainCommand. This also required a refactor of the command to allow for it to be called by user action or the background job.
