fix(layout): correct sidebar toggle behavior and navigation logic

- Remove `onClick` toggle handler from `Sidebar` links to prevent unwanted state changes during navigation.
- Remove aggressive `onClick` auto-collapse from `MainLayout` content wrapper so the sidebar remains stable.
- Ensure sidebar state is exclusively managed by the dedicated toggle button, aligning with standard desktop UX.
