Fix security.yml YAML syntax + Make setup.py more robust

🔧 Security Workflow Fixes:
- Recreate security.yml with proper YAML syntax
- Remove all Trivy references completely
- Fix Unicode encoding issues
- Clean up emoji characters causing parsing errors
- Remove docker-security-scan job entirely
- Update security-summary dependencies

📦 Setup.py Improvements:
- Add try/catch for requirements.txt reading
- Provide fallback requirements if file not found
- Prevents FileNotFoundError during build process
- More robust package installation

 Result:
- Valid YAML syntax in security.yml
- No more line 25 parsing errors
- Build process won't fail on missing requirements.txt
- Cleaner, Trivy-free security workflow
