Subject: [PATCH] Fix Open WebUI storage and model detection

- Change emptyDir to persistent volume (open-webui-data PVC)
  Fixes data loss on pod restart (admin user disappears)

- Add ENABLE_OLLAMA_API=false
  Disable broken Ollama endpoint probing
  vLLM uses OpenAI-compatible API, not Ollama

- Create pvc.yaml for persistent data storage
  10Gi NFS-backed storage via nfs-emporium StorageClass
