refactor(chat): replace useSnapScroll with StickToBottom for smoother scrolling

The useSnapScroll hook has been replaced with the StickToBottom component to improve the scrolling behavior in the chat interface. This change ensures smoother and more consistent scrolling, especially when new messages are added. The StickToBottom component provides better control over the scroll position and handles edge cases more effectively.
