WHY IT NEEDS A POLICY

Why vtex_deny_sku needs a policy

Denying a SKU modifies its status in the catalog, preventing it from being listed/sold. This is a Write operation as the status change is reversible (the SKU can be approved later). It has medium severity because misuse could block legitimate products from being sold on the marketplace.

From the tool's definition 'Deny a seller SKU' — this changes the approval status of a SKU, which is a reversible state modification (it can be re-approved or re-submitted).
