Implement Google Books API integration for book updates and enhance library management features

- Added a new endpoint in `index.js` to update book data using the Google Books API, allowing for real-time updates based on ISBN.
- Introduced a `rebuild_book_entries` function in `libraryManager.py` to facilitate user-driven updates of book entries from the Google Books API.
- Enhanced error handling and user prompts for better interaction during book updates.
- Updated `public/index.html` and `public/script.js` to improve the user interface and support new functionalities.
- Modified styles in `public/styles.css` to enhance the layout and usability of the checkout button and location prompt.
