fix: resolve container build issues

- Add missing build:electron script to package.json
- Switch from Alpine to Debian Bullseye for better compatibility
- Simplify Dockerfile and Singularity definition
- Fix GitHub Actions workflow for proper Docker/Singularity builds
- Remove multi-platform builds to avoid complexity
- Use xvfb-run directly in CMD for headless mode
