Remove unused favicon.svg and enhance language dropdown initialization and event listener management

- Deleted the unused favicon.svg file to clean up the assets.
- Improved the LanguageDropdown component by preventing multiple initializations and ensuring proper cleanup of old event listeners to enhance performance and user experience.
- Updated BasicScripts to handle event listener removal more gracefully, preventing errors if elements are no longer in the DOM.
