Feature: Docker deployment configuration

- Добавлена поддержка docker-compose для развертывания
- STATIC_ROOT автоматически переключается в prod (/Volume1/DockerAppsData/npm/data/static/)
- Добавлены ALLOWED_HOSTS и CSRF_TRUSTED_ORIGINS из env переменных
- Улучшена обработка .env файла (проверка существования)
- Добавлен gunicorn в requirements.txt
- Добавлены .dockerignore, Dockerfile, docker-compose.yml
- Добавлены example файлы для .env.docker и entrypoint.sh
- Обновлен .gitignore для исключения файлов с секретами
