Add Open Web UI AI Chat Container and Nginx Proxy

Introduce a new container definition for the Open Web UI AI Chat service
in `OpenWebui.nix`, specifying its Docker image, volume, and environment
variables. This change includes the addition of a new port in `Ports.nix`
to facilitate communication with the service.

Furthermore, configure Nginx to serve the AI Chat application by adding
a new virtual host entry in `Web.nix`, ensuring SSL is enforced and
websocket support is enabled. This setup allows for a seamless
integration of the AI Chat service into the existing infrastructure,
improving accessibility and security.
