code-to10 v6 A12: scorecard example renamed to 2026-10-31 snapshot with timeliness fields

(cherry picked from commit 633cdbc94e7a7b0c5d3b0b135189faf3de6673f4)

Reconcile-port: handler_admin.py hunks redirected into cloud/server.py _audit_scorecard (target keeps 6-mixin split; scorecard module itself applied cleanly).
