Pull request overview

This pull request adds a new CodeQL Advanced workflow configuration file to enable automated security scanning for the JavaScript/TypeScript code in this HTML/JavaScript project. However, there is a significant discrepancy between the PR title and the actual changes being made.

Changes:

• Adds a new CodeQL workflow file that runs on pushes and pull requests to the main branch, as well as weekly on Fridays at 17:40 UTC
• Configures JavaScript/TypeScript language analysis with no build mode (appropriate for this client-side HTML/JavaScript project)
• Sets up proper permissions and uses the latest GitHub Actions (v4) for CodeQL scanning
