Adds a new `lobechat` group and task to the `ai-frontend.nomad` job file.
This change introduces the LobeChat AI frontend application, running in a Podman container, alongside the existing OpenWebUI service. It's configured to connect to an Ollama instance via Consul service discovery.
The new `lobechat` service is registered in Consul but does not include Traefik tags, meaning it's not immediately exposed via the Traefik ingress controller. It's constrained to run on the `hp1-home` host.
