🔧 Fix Docker lowercase repository name issue and add robust testing workflow

- Fix Docker tag lowercase requirement in GitHub Actions workflow
- Add comprehensive testing workflow without Docker push dependency
- Add repository name lowercase transformation for Docker images
- Add detailed security analysis and status reporting
- Add fallback workflow for cases where Docker push might fail
- Add comprehensive test reporting and status documentation
- Ensure compatibility with GitHub Container Registry naming requirements

This addresses the Docker repository name case sensitivity issue while
providing a robust testing workflow that works regardless of Docker push status.
