identity: "disconnect app" — revoke_app(Subject, Client) (+4 tests)

identity_tokens:revoke_app(Subject, Client) revokes every grant a subject
holds for one client at once (audited one revoke per grant), exposed at the
facade as identity:revoke_app. The action counterpart to the grants view —
completing the account-security view+action pairs (sessions/logout_all,
grants/revoke_app, history). Other subjects' same-client grants are
untouched. account 11/11, 233/233.
