- Reduced Docker image sizes
- Removed RaSCSI references in various areas (e.g. rascsi -> backend)
- Added compilation-only step to easyinstall.sh
- Moved apt package lists to variables
- Revert to triggering GitHub Actions runs on push
- Updated web/frontend_checks workflow to run black and flake8 against all Python sources
