fix(sidebar): persist sidebar state across page navigation

- Move `isSidebarOpen` state from local component (`useState`) to global Zustand store (`ui-store.ts`).
- Fix an issue where the sidebar would incorrectly reset to its default closed state when navigating between routes (e.g., to the Telemetry page) due to component remounting.
- Ensure consistent sidebar toggle behavior across the entire dashboard application.
