Implement Fullstack Authentication with JWT and Backend Integration

[harish-pasupuleti]

📋 Description
This PR implements a full authentication and backend integration for the application.

✅ Backend Enhancements:

Created a new backend/ folder containing:

auth routes with Sign In / Sign Up using JWT authentication

goals and transactions routes connected to MongoDB

Added .env file with environment variables:

MONGODB_URL=<Your MongoDB connection string>
JWT_SECRET=<Your JWT secret key>
Frontend_URL=http://localhost:5173

✅ Frontend Enhancements:

Added AuthModal component for a Sign In / Sign Up dialog box.

Updated TransactionContext to fetch data from the backend instead of local mock data.

Integrated JWT authentication — token is stored securely and attached in headers for API requests.

Improved API structure to handle user-specific data for goals and transactions.

Fixes # (Complete backend & frontend integration with authentication system)

This problem has been pending for over a week. I’ve completed all backend work including:

MongoDB integration

JWT authentication and verification

Adaptive frontend for login
