Subject: [PATCH] feat(layout): Replace top navbar with sidebar layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add new sidebar-based layout components:
  - AppLayout.vue: Main layout wrapper with sidebar + topbar
  - AppSidebar.vue: Desktop sidebar with navigation, theme, language
  - AppTopBar.vue: Top bar with notifications, cart, profile
  - MobileDrawer.vue: Slide-out drawer for mobile navigation
- Add Shadcn Sheet component for mobile drawer
- Update App.vue to use new AppLayout (except login page)
- Rename old Navbar.vue to Navbar.old.vue for reference

Layout structure:
- Desktop: Fixed 288px sidebar + offset content area
- Mobile: Hidden sidebar with drawer triggered from top bar
- Cart only shown when market module is enabled
- Combined notifications (chat unread count)
