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.
- Refined the inner padding logic in SiderBar to maintain consistent behavior when selecting items.
- Introduced a new function in Style context to manage sider visibility based on the current pathname, enhancing responsiveness to navigation changes.
