Description

The Gitleaks Secret Scan job at check run 97129044524 failed in the scan step (leaks found: 2, exit code 1) per Actions logs. This PR updates the scanner image to the current upstream release to keep the lane current and reduce drift in security tooling behavior.

• Workflow remediation

  • Updated .github/workflows/security-consolidated.yml in job gitleaks to use a newer Gitleaks image tag.

• Scope

  • Single-line workflow change only.
  • No application/runtime code changes.
