What logout-all does on Moxis

WHY IT NEEDS A POLICY

Why logout-all needs a policy

Logging out from all registered instances is a reversible write/state-change operation — it terminates active sessions across all instances, but sessions can be re-established via login. It is not destructive (no data deleted), not financial, and not merely a read. The blast radius is medium since misuse would disrupt access to all registered MOXIS instances simultaneously, requiring re-authentication.
