docs(openwebui): frank-dragoon enabled in the picker beside frank-zealot

Live DB trio applied on Dankclaw (enable idx 0, model row + global
access_grant, restart); verified /api/models as admin and role=user,
chat answers pong. Battery rewritten to gate on /api/models —
/api/v1/models/list lists only workspace models on 0.6.x.

+## 2026-10-09 — OpenWebUI picker: `frank-dragoon` enabled beside `frank-zealot`
+
+- Per Frank: make `frank-dragoon` (service `frank-large`, halogen
+  flash-server, `host.containers.internal:7770`) selectable in OpenWebUI. The
+  connection (idx 0) already carried `model_ids: ["frank-dragoon"]` from the
+  wire rename; it lacked the other two legs of the trio: `enable: false`, no
+  `model` row, no `access_grant`.
+- Applied on the live DB (snapshot `webui.db.bak-20261009b`): idx 0
+  `enable: true`; `model` row `frank-dragoon` with
+  `params.context.length = 262144` (per-slot `HALOGEN_CTX`) and the v2
+  abliterated description; `access_grant`
+  `(model, frank-dragoon, user, *, read)`. Then
+  `systemctl --user restart open-webui.service` (drops cached model list;
+  browser JWTs die with it — expect one SSO re-round-trip per tab).
+- Verified: `/api/models` lists `frank-dragoon` as admin AND as the QA
+  `role='user'` account (picker truth, key `data`); `POST
+  /api/chat/completions` through the app answers `pong` at `max_tokens
+  1500`. `/api/v1/models/list` reads `items: []` for connection-backed
+  models on this 0.6.x image (pre-existing for `frank-zealot` too) — the
+  battery in [[OpenWebUI]] is rewritten to gate on `/api/models`.
+- Docs: [[OpenWebUI]] Facts/LLM-backends/battery/history updated;
+  `frank-archon` (idx 1, Dankserver) intentionally stays disabled.
