fix(sidebar): toggle sidebar state when clicking navigation links

- Update the `onClick` handler for navigation links in `sidebar.tsx` to use `!isSidebarOpen` instead of a hardcoded boolean.
- Enable navigation items to act as smart toggles: expanding the sidebar when clicked in collapsed mode, and collapsing it when clicked in expanded mode.
- Improve overall user experience by reducing the need to manually click the main toggle button.
