Added useEffect hook with event listener to close the methodology panel
when user clicks outside of it. This provides better UX by allowing users
to close the panel by clicking anywhere outside, not just the header.
Changes:
- Added componentRef using useRef to track the component DOM element
- Added useEffect with mousedown event listener
- Wrapped Card component in div with ref
- Event listener automatically cleans up when panel closes or component unmounts
