Missing page: Admin Dashboard (/admin)

Problem

The /admin route is not implemented in the application. When users try to navigate to /admin, they see an empty page with a console warning: "No routes matched location '/admin'"

Note: There appears to be an /admin/products route that redirects to home, suggesting some admin functionality was planned.

Expected Behavior

Admin users should have access to an admin dashboard with:

• Overview of orders, products, and users
• Quick stats and analytics
• Links to admin sections (products, orders, users)
• Management tools for the e-commerce platform

Current Behavior

• Navigation to /admin shows an empty page
• Console warning: "No routes matched location '/admin'"
• Navigation to /admin/products redirects to homepage
• No admin dashboard or management interface

Acceptance Criteria

• Create /admin route in React Router
• Implement Admin Dashboard component
• Display key metrics (total orders, revenue, products, users)
• Add navigation to admin sections (products, orders, users)
• Implement admin authentication/authorization
• Create layout for admin section with sidebar navigation
• Fix /admin/products route (currently broken)
• Add role-based access control
• Show recent orders and activities

Priority

Medium - Important for administrative management but not customer-facing

Start by tracing the React Router entries for /admin and /admin/products, then read the existing AdminProducts component. Use the acceptance criteria to define the dashboard scope, including metrics, recent activity, section navigation, layout, authentication, and role-based access; completion requires the routes and admin access behavior to work without redirecting to the homepage.
