feat(open-webui): deploy Open WebUI with litellm backend

Deploys Open WebUI (chat.k8s.syd1.au.unkin.net) into the open-webui namespace via the aitooling ArgoCD project. Uses SQLite with a 10Gi cephrbd PVC for persistence, routes model requests to the existing litellm deployment, and exposes the UI through the traefik-external gateway. Credentials (OPENAI_API_KEY, WEBUI_SECRET_KEY) are injected via VaultStaticSecret from kv/kubernetes/namespace/open-webui/default. Closes #155
