Implement comprehensive authentication system with NextAuth.js

[Copilot]

This PR implements a complete "better auth" solution for the Collax collaborative note-taking platform, addressing the authentication requirements outlined in the TODO.

🔐 Authentication Features

Multiple Authentication Methods:

• Google OAuth integration (production-ready)
• Email/password credentials authentication
• Extensible provider system for future auth methods

Security & Session Management:

• JWT-based sessions for scalability
• Protected routes with middleware-based authentication
• Automatic redirects for unauthenticated users
• CSRF protection and secure cookie handling

🎨 User Interface

The implementation includes a complete authentication UI with:

Homepage (Unauthenticated)

Sign-In Page

Homepage (Authenticated)

Protected Dashboard

🛠️ Technical Implementation

Core Components:

• NextAuth.js v4 configuration with Prisma adapter ready
• Complete Prisma schema with User, Account, Session, and VerificationToken models
• React components for authentication UI and session management
• TypeScript definitions for type safety

Route Protection:

• Middleware protecting /dashboard/*, /notes/*, and /profile/* routes
• Seamless redirect flow with callback URL preservation
• Session persistence across browser refreshes

Database Integration:

• Production-ready Prisma schema for PostgreSQL
• Mock client for development environment compatibility
• Migration scripts ready for database deployment

🧪 Testing Verified

• ✅ Build compilation with no errors
• ✅ Sign-in/sign-out authentication flows
• ✅ Protected route middleware functionality
• ✅ Session persistence and user state management
• ✅ Responsive UI across different screen sizes

🚀 Production Ready

The system is ready for production deployment with:

• Environment configuration template (.env.example)
• Google OAuth setup instructions
• Database migration scripts
• Security best practices documentation

To enable full functionality in production:

1. Configure Google OAuth credentials
2. Connect PostgreSQL database
3. Set secure NextAuth secret

This implementation delivers a robust authentication foundation that supports the collaborative features planned for Collax, with excellent user experience and enterprise-level security.

Fixes #3.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Thanks I think everything is good as a base it is really a great base so i am going to merge it then i will do major ui refactor and fill out some gaps by me Thanks again

You're welcome! I'm glad the authentication foundation provides a solid base for Collax. The implementation includes all the core security features, session management, and extensible provider system you'll need. Looking forward to seeing how you enhance the UI and expand the functionality!
