feat: implement chat history deletion functionality

Added a new DELETE endpoint to allow users to clear their chat history. This functionality ensures that while the chat messages are removed, any credits spent remain intact. Additionally, updated the ListemGovde component to reflect changes in user preferences and integrated a modal for notifying users about preference changes. Enhanced the SohbetClient component to include a button for clearing chat history, improving user experience and interface clarity.
