fix: Correct inner padding and sider visibility logic in HeaderBar, PageLayout, and SiderBar components
- Updated the click handler in HeaderBar to toggle inner padding and sider visibility correctly based on the selected item.
- Adjusted the conditional rendering of SiderBar in PageLayout to ensure it displays when the sider is shown.
