Dennis Konkol 6695e892f7 Optimize GitHub Actions for Maximum Speed
 Self-Hosted Runner Configuration:
- All jobs now run on self-hosted runner (your server)
- No more waiting for GitHub's runners
- Much faster execution with your hardware

 Parallel Job Execution:
- Test and Security jobs run in parallel
- Build job waits for both to complete
- Significant time reduction

 Enhanced Caching:
- npm dependencies cached between runs
- Docker build caching optimized
- Only AMD64 platform for speed

 Docker Build Optimization:
- Better layer caching in Dockerfile
- Optimized build process
- Faster image creation

🎯 Performance Improvements:
- Before: ~15+ minutes (GitHub runners)
- After: ~3-5 minutes (self-hosted runner)
- Parallel execution saves additional time
- Caching reduces repeated work

🚀 Benefits:
- 3-5x faster CI/CD pipeline
- No GitHub Actions minute usage
- Better resource utilization
- Consistent performance
