feat(layout): auto-collapse sidebar when clicking main content area

- Import `useUiStore` into `main-layout.tsx` to access the global sidebar state.
- Add an `onClick` event listener to the main content wrapper.
- Automatically close the sidebar if it is expanded and the user clicks outside of it.
- Enhance overall UX by providing a more intuitive, frictionless way to dismiss the navigation menu.
