Refactor Scraper Dockerfile and Add Entrypoint Script

- Replaced inline entrypoint script creation in the Dockerfile with a separate entrypoint.sh file for better maintainability and clarity.
- The new entrypoint script handles one-time scraping with date range support, improving the scraper's functionality and usability.
