Assets - Implement administrative freeze and un-freeze functionality for all services in MHR/PPR

SBC FIN has requested this - Require the ability to freeze any paid product in MHR/PPR due to NSF when a filing is submitted.

This would be applicable only to products that can be revoked. e.g. searches can't be revoked

The issue names MHR/PPR and asks for administrative freeze and un-freeze functionality, but does not identify files, tests, or entry points. First clarify which services and revocable paid products are in scope, and what the freeze and un-freeze behavior should be. Done means the agreed functionality covers applicable products while excluding products that cannot be revoked, such as searches.
