Build me a full stack app called Collab Sphere for influencers and brands to work together.

I want people to be able to sign up and log in as either an influencer or a client, make their profile, upload images, and manage their info. Influencers should be able to create promotion campaigns, clients should be able to browse influencers, leave ratings and reviews, and both sides should have dashboards that show their activity. Add real time one to one chat with online status, so they can message each other and see new messages instantly. Also include a simple AI helper that can answer questions about how the platform works. Use a clean modern design that feels polished and easy to use, and make sure the app handles authentication securely.

If you need to, look up current docs online for any libraries or setup details, and keep everything working across the frontend, backend, and chat service.
