Build me a full MERN app called Explore India for a tourism website. I want a React frontend with a clean home page, destinations listing, trip planner, login and signup, favourites, and a simple admin style manage page where I can add, edit, and delete destinations. The backend should use Node and Express with MongoDB and Mongoose, and it should have working API routes for items, auth, itineraries, plans, favourites, and enquiries. Please include JWT login, hashed passwords, and make sure signed in users can save favourites and trip plans to the database, while guests can still use favourites in the browser.

Use Axios for the frontend API calls and React Router for navigation. Add a navbar, footer, toast messages, and basic responsive styling so it feels polished. Seed the database with sample India travel data so the app works right away. If you need anything unclear, look up current docs online and keep the setup simple so I can run it locally with one command for frontend and one for backend.
