feat: initialize serverAppConfigs with podman stacks for Dankserver and Dankclaw

- Dankserver stack: RomM, Copyparty, Calibre-Web, node-exporter
- Dankclaw stack: Gluetun VPN (SearXNG tunnel), SearXNG+Valkey, ComfyUI
  (CPU backend), OpenWebUI, Hermes, Gitea+Postgres (migrated), Caddy
  reverse proxy, Grafana+Prometheus+Loki+Alloy observability
- Caddyfiles with .local hostname convention and basicauth homepage
- bind-mount storage policy, no named volumes
- deploy.sh mirroring vllmScripts git workflow (push -> pull -> restart -> health)
- docs/ Obsidian vault: per-service docs from frank-default-small research
  subagents (promtail EOL -> Alloy; gitea SECRET_KEY preservation; ComfyUI --cpu)
- bats test suite at 6 seams — 22 tests green

+# OpenWebUI
+
+OpenWebUI is a self-hosted chat interface for LLMs. It connects to OpenAI-compatible endpoints, Ollama, llama.cpp, and vLLM, and adds RAG, plugins, tool calling, and multi-user support.
+
+**Host:** Dankclaw — **Hostname:** `chat.dankclaw.local` — **Port:** 3000 — **Docs:** https://github.com/open-webui/open-webui
+
+## Facts (from research, primary source)
+
+| Item | Value |
+|------|-------|
+| Image | `ghcr.io/open-webui/open-webui:main` (CPU build for non-NVIDIA hosts) |
+| Port | 3000 (host) → 8080 (container) |
+| Data volume | config, sessions, RAG indexes |
+| Backend | OpenAI-compatible endpoint at `http://localhost:7770/v1` (llama.cpp) |
+
+> Note: the `:cuda` image tag was previously used on Dankserver. Dankclaw is AMD; use the default (CPU) image, NOT the cuda tag.
+
+## Connecting to llama.cpp
+
+OpenWebUI talks to the local llama.cpp server through its OpenAI-compatible API. Configure a new connection in the UI or set the base URL:
+
+```yaml
+environment:
+  OPENAI_API_BASE_URL: "http://host.containers.internal:7770/v1"
+  OPENAI_API_KEY: "none"
+```
+
+The hostname `host.containers.internal` reaches the podman host where llama.cpp listens on 7770.
+
+## Volumes
+
+| Container path | Host path (convention) |
+|----------------|------------------------|
+| `/app/backend/data` | `/opt/openwebui/data` |
+
+## Healthcheck
+
+OpenWebUI responds on `/health` with 200.
+
+## Gotchas
+
+- Use the non-CUDA image on AMD hosts.
+- The default admin account is created on first login; secure it immediately.
+- If the backend (llama.cpp) is slow to load, OpenWebUI may show connection errors until the model is ready — that matches the known 3–8 minute model load time.
