feat(chat): add scroll-to-bottom button for chat messages

Browse Source 
Introduce a `ScrollToBottom` component that displays a button when the user is not at the bottom of the chat, allowing them to quickly scroll to the latest message. This improves user experience by making it easier to navigate long chat histories.
