Build me a self hosted WhatsApp gateway and dashboard where I can connect multiple WhatsApp accounts by scanning QR codes, see each session in one place, and manage everything from a clean admin screen.

I want to be able to send messages through an API, schedule text and media messages for later, set up simple auto replies based on keywords, and forward incoming events to my own webhook URLs. Please include basic contact management, session status, and a way to create and manage an admin user. It should also have docs or a built in API page so I can understand the endpoints easily.

Make it production ready, with a database backed setup, secure login, and an experience that feels like a real dashboard rather than a rough script. If you need to check current library docs online while building it, go ahead.
