Refactor book management system:

- Updated .gitignore to exclude node_modules directory. - Enhanced index.js with new endpoints for book fetching and checkout requests, integrating nodemailer and express-rate-limit for email notifications and request management. - Added functionality to confirm book presence in the library and improved error handling for external book sources. - Updated package.json and package-lock.json to include new dependencies (nodemailer, express-rate-limit) and their respective versions. - Modified public HTML and JavaScript files to support new features, including a confirm mode for book scanning and improved UI elements. - Updated styles for better user experience in the library interface.
