SHA-pin GitHub Actions and upgrade deprecated checkout versions

- Upgrade actions/checkout from v2/v3 to SHA-pinned v4
- SHA-pin all unshelled action tags (pages, CodeQL, scorecard,
  rust-cache, upload/download-artifact, setup-node, cache)
- Standardise scorecard-action to v2.4.0
- Fix setup-node@v6 → SHA-pinned v4
