refactor: streamline HTML structure and enhance UI components
- Cleaned up the HTML structure in index.html and pdf-multi-tool.html for better readability and maintainability. - Improved the user interface of the PDF multi-tool with responsive button designs and better layout. - Added new CSS styles for button states and cursor behavior. - Updated README with corrected Docker deployment link. - Refactored JavaScript logic to utilize new helper functions for formatting star counts. - Commented out unused attachment functionalities in the logic files for future integration.
