setup react router 4

[EDOHWARES]

Description

This PR addresses issue #4 by setting up React Router v6 and defining all top-level application routes centrally.

Changes Made

• Installed react-router-dom dependency.
• Created AppRouter.jsx to configure the <BrowserRouter> and define application-wide routing.
• Set up a nested MainLayout using <Outlet /> for consistent navigation and page structure.
• Created placeholder page components for all core routes:
  • Home (/)
  • Explore (/explore)
  • CreateCampaign (/create)
  • CampaignDetails (/campaign/:id)
  • Dashboard (/dashboard)
  • Admin (/admin)
  • Login (/login)
  • Register (/register)
  • NotFound (*) - Handles 404s.
• Cleaned up App.jsx to render the router instance instead of placeholder boilerplate.
