WHY IT NEEDS A POLICY

Why restore_campaign_snapshot needs a policy

Restoring from a snapshot overwrites current campaign state with an earlier version. This is a Write operation (reversible in principle, since the snapshot exists), but it is high severity because it replaces all current campaign data — characters, inventory, quests, logs — potentially losing any unsaved progress since the last snapshot.
