feat(openwebui): deploy Open WebUI v0.11.3 with Pocket ID OIDC (DEV-567)

Adds the Open WebUI stack at openwebui.basicstack.de:

- Namespace `openwebui`, ArgoCD Application with auto-sync + selfHeal
- Own Postgres 16 + pgvector (`pgvector/pgvector:pg16`, 20Gi encrypted PVC,
  fsn1-pinned); VECTOR_DB=pgvector, extension auto-created
- Own Redis 7 (2Gi encrypted PVC, fsn1-pinned) used both as cache and as
  websocket manager (db=1)
- Hetzner Object Storage bucket `openwebui-basicstack` (hel1, path-style)
  for file uploads; shared project S3 credentials
- Traefik ingress + Let's Encrypt TLS
- Pocket ID client `Open WebUI` (PKCE on) restricted to groups
  `openwebui_admins` and `openwebui_users`; `andreas.leinen@basicstack.de`
  is member of both and gets admin via OAUTH_ADMIN_ROLES
- Password login disabled (`ENABLE_LOGIN_FORM=false`, `ENABLE_SIGNUP=false`)

+# Open WebUI (openwebui.basicstack.de)
+
+Self-hosted LLM front-end — [Open WebUI](https://openwebui.com/).
+
+## Stack
+
+- **App:** `ghcr.io/open-webui/open-webui:v0.11.3` (Deployment, 1 replica, `Recreate` strategy)
+- **Database:** Postgres 16 + pgvector (`pgvector/pgvector:pg16`, StatefulSet, PVC 20Gi on `hcloud-volumes-encrypted`)
+- **Vector DB:** `pgvector` in the same Postgres instance (`VECTOR_DB=pgvector`, extension auto-created on first start)
+- **Cache / websocket manager:** Redis 7 (StatefulSet, PVC 2Gi on `hcloud-volumes-encrypted`, `WEBSOCKET_MANAGER=redis` on `db=1`)
+- **Object storage:** Hetzner Object Storage bucket `openwebui-basicstack` (region `hel1`, path-style)
+- **Auth:** Pocket ID OIDC — `Open WebUI` client, restricted to `openwebui_admins` / `openwebui_users`. Sign-up via OAuth only (`ENABLE_LOGIN_FORM=false`, `ENABLE_SIGNUP=false`)
+- **Ingress:** Traefik, TLS via `letsencrypt-prod` (DNS-01)
+- **Node placement:** all stateful pods pinned to Hetzner location `fsn1` (matches CSI-encrypted PVCs)
+
+## Files
+
+| File | Purpose |
+| ---- | ------- |
+| `namespace.yaml` | Namespace declaration |
+| `postgres.yaml` | Postgres+pgvector StatefulSet + Service (fsn1-pinned) |
+| `redis.yaml` | Redis StatefulSet + Service (fsn1-pinned) |
+| `openwebui.yaml` | App Deployment + Service + Ingress (+ PVC for local cache) |
+| `postgres-credentials-sealed.yaml` | Sealed Postgres user/db/password |
+| `app-secrets-sealed.yaml` | Sealed `WEBUI_SECRET_KEY`, `DATABASE_URL`, `PGVECTOR_DB_URL`, `REDIS_URL`, `WEBSOCKET_REDIS_URL` |
+| `oidc-sealed.yaml` | Sealed OIDC client id + secret |
+| `s3-sealed.yaml` | Sealed S3 access key, secret, endpoint, region, bucket |
+
+## Deployment references
+
+- Argo Application: `apps/app-openwebui.yaml`
+- Pocket ID OIDC client id: `3ffbd06b-12cc-4562-bbe5-da4433962870` (PKCE **enabled**, group restriction on, allowed groups: `openwebui_admins`, `openwebui_users`)
+- Pocket ID groups: `openwebui_admins` (`737f4b7f-63f2-42b5-98bb-4e96c4a80546`), `openwebui_users` (`74b0af52-0942-4cb6-b37a-83d87d203e32`)
+- OIDC redirect URI: `https://openwebui.basicstack.de/oauth/oidc/callback`
+- Role mapping: OIDC `groups` claim → Open WebUI roles. `openwebui_admins` → admin, `openwebui_users` → user.
+- Initial admin: `andreas.leinen@basicstack.de` (member of both groups; `OAUTH_ADMIN_ROLES=openwebui_admins`)
+- DNS: `openwebui.basicstack.de` A → `138.199.128.63` (cluster ingress)
+- S3 endpoint: `https://hel1.your-objectstorage.com` bucket `openwebui-basicstack` (CORS whitelisted to `https://openwebui.basicstack.de`). S3 credentials are shared with the Hetzner project (same key used for `outline-basicstack`, `basicstack-backup`).
+
+## Deferred / follow-ups
+
+- **Model providers (Ollama / OpenAI):** none wired yet. Add `OLLAMA_BASE_URL` or `OPENAI_API_BASE_URL`/`OPENAI_API_KEY` via a sealed secret when a backend is chosen.
+- **RAG embeddings:** `RAG_EMBEDDING_ENGINE=default` (local). Switch to `openai` + `RAG_OPENAI_*` for hosted embeddings when a provider is picked.
+- **Content extraction (Tika):** not deployed. Add `CONTENT_EXTRACTION_ENGINE=tika` + `TIKA_SERVER_URL` once a Tika service is available if PDF/Docx ingestion is required.
+- **SMTP:** Open WebUI has no built-in mailer; not wired.
+- **HA:** single replica with `Recreate` strategy; Redis websocket manager already in place, so scaling to N replicas only requires bumping `spec.replicas` (Postgres/Redis remain single-instance).
