ci(quality): unblock v3.8.27 release gates (zizmor pin + test-masking allowlist)

- zizmor ratchet (151→139, no regression): SHA-pin every action ref ADDED this
  cycle — codeql/dast-smoke/semgrep (3 new workflows) + trivy-action (docker-publish)
  + actions/cache (nightly-mutation). Pre-existing tag refs keep the repo convention.
- test-masking: add config/quality/test-masking-allowlist.json + allowlist support in
  check-test-masking.mjs (exempts ONLY the net-assert-reduction signal; tautology/skip/
  deletion still fire). Allowlists 2 verified-legitimate reductions:
  appearance-widget-settings-schema (#4033 removed showTokenSaverOnEndpoint field) and
  dashboard-shell-tabs (#3973 tabs→redirect refactor, asserts replaced). +4 gate tests.
