Introduces a navigation drawer that can be toggled and persists its state in localStorage. The drawer displays route items and adapts its location and permanence based on device type. Also refactors initial drawer visibility and updates the app bar navigation icon to toggle the drawer.
Replaced App.vue with Layout.vue to serve as the main layout. Added Home and 404NotFound route components and configured router to handle home and fallback routes. Updated main.ts to use the new layout component.
