refactor(docker): przenieś skrypt startowy do osobnego pliku

- Utworzono scripts/test_start_extension.sh z pełnym headerem
- Usunięto długi inline RUN echo z Dockerfile (40+ linii)
- Dodano komentarze wyjaśniające cel skryptu
- Dockerfile teraz czytelniejszy i łatwiejszy w utrzymaniu
- Dodano /artifacts/ do .gitignore (docker buildx output)

Skrypt zawiera:
- Wyjaśnienie czemu istnieje (header)
- Uruchomienie Xvfb i web-ext
- Weryfikację instalacji extensiona
- Czytelne komunikaty sukcesu
