Restructure the chatbot page to follow this 3-zone layout:
Left Side (70%) → Chat area (no logic or UI change, keep as-is)
Right Side (30%) → View Past Chats panel (new component – you can display the fist few words of the chat along with date and role, for more than one chats, club them under the date). This pane shld be always visible.
Allow users to export chats as pdf.
Bottom Full Width → Chatbot stats (no logic or UI change, keep as-is)
This is purely a layout refactor. All functionality must remain intact.
