Revert and drift

Applied proposals appear with a Revert button. Revert restores the state captured just before the change; it does not ask an AI to undo anything. Coupons the proposal created are moved to the trash, and updated coupons go back to their earlier values.

Before reverting, Store Steward checks for drift: whether the touched objects were changed after the proposal was applied. If they were, the revert is refused and you are told so. Choose Revert anyway to overwrite those later changes. Forced reverts are recorded in the audit log.
