fix: Windows cross-platform support (#310)

- Add stdout UTF-8 wrapper in config.py and check_prerequisites.py
  to prevent UnicodeEncodeError on Windows cp1252 terminals
- Add .gitattributes to force LF line endings on shell scripts,
  preventing CRLF breakage in Linux containers
- Remove emoji from docker/entrypoint.sh
- Update test_pages_render_without_errors routes to match
  /demo/cineflow/ prefix after recent refactor

Closes #309
