Enhance RocketChat livechat initialization and improve smooth scrolling in BasicScripts

- Refactored the RocketChat livechat widget initialization to prevent multiple initializations and ensure proper loading of the script, improving performance and user experience.
- Implemented a mechanism in the BasicScripts component to manage event listeners for smooth scrolling, allowing for cleanup of old handlers to prevent memory leaks.
