refactor(layout): implement responsive sidebar and synchronize mobile menu

- Create a new `Sidebar` component for desktop with collapse/mini-sidebar feature.
- Rename `navbar.tsx` to `mobile-header.tsx` to better reflect its mobile-specific purpose.
- Synchronize icons (from lucide-react) and menu labels between desktop `Sidebar` and touch-based `MobileNav`.
- Fix 'Logout' button sizing in the mobile menu by removing forced margins for better responsiveness on narrow screens.
- Remove conflicting 'aria-hidden' attribute in MobileNav to resolve browser accessibility (a11y) warnings.
- Add a spacer in `main-layout.tsx` to prevent the bottom content from being overlapped by the fixed Footer.
