chore: Implement CodeQL CI Alignment and Security Scanning

- Added comprehensive QA report for CodeQL CI alignment implementation, detailing tests, results, and findings.
- Created CodeQL security scanning guide in documentation, outlining usage and common issues.
- Developed pre-commit hooks for CodeQL scans and findings checks, ensuring security issues are identified before commits.
- Implemented scripts for running CodeQL Go and JavaScript scans, aligned with CI configurations.
- Verified all tests passed, including backend and frontend coverage, TypeScript checks, and SARIF file generation.
