Wire node-static deploy for chat_web_app (closes #13).

Add build:prod/beta webroot scripts, Gitea CI/deploy workflows, and bake API
URLs from REACT_APP_* so hosts can deploy via server-infra like dta_webapp.

+# Chat Bot Frontend (`chat_web_app`)
+
+CRA/React app under `llm-fe/`. Production serve is **node-static** (not Docker):
+hosts build with npm and write into `/var/www/...`; the shared **web-static** nginx
+container serves those roots. Deploy is driven by `server-infra`.
+
+## Local development
+
+```bash
+cd llm-fe
+npm ci
+npm start
+```
+
+Uses `.env.development` (API → local `chat_backend`, usually `http://127.0.0.1:8001`).
+
+## Environment files (CRA `REACT_APP_*`)
+
+| File | When used | Backend |
+|------|-----------|---------|
+| `.env.development` | `npm start` | local backend |
+| `.env.production` | `npm run build` / `build:prod` | `https://chatbackend.aimloperations.com` |
+| `.env.beta` | `npm run build:beta` | `https://beta.chatbackend.aimloperations.com` |
+
+Baked into the JS bundle at build time. No host secret file needed for this
+frontend (unlike Django apps under `~/Documents/secrets/`).
+
+Required vars:
+
+- `REACT_APP_BACKEND_REST_API_BASE_URL` — REST base (trailing `/api/`)
+- `REACT_APP_BACKEND_WS_API_BASE_URL` — WebSocket URL (full `ws://` / `wss://` path)
+
+## Production / beta build (host deploy)
+
+`server-infra` runs `npm ci` then `npm run build:<env>` in `llm-fe/`. Those
+scripts write static assets into:
+
+| Script | Document root |
+|--------|----------------|
+| `npm run build:prod` | `/var/www/prod.chat.aimloperations/html` |
+| `npm run build:beta` | `/var/www/beta.chat.aimloperations/html` |
+
+Paths must match `server-infra` `app_catalog.chat_web_app.webroot_pattern`.
+
+Manual deploy from the control node:
+
+```bash
+~/Documents/repos/server-infra/scripts/deploy.sh \
+  --app chat_web_app --env prod --ref <sha>
+```
+
+## CI / CD (Gitea)
+
+- `.gitea/workflows/unit-tests.yml` — tests on push/PR to `master`
+- `.gitea/workflows/deploy-prod.yml` — after green Unit Tests on `master` push
+- `.gitea/workflows/deploy-beta.yml` — manual (`workflow_dispatch`)
+
+## Tests
+
+```bash
+cd llm-fe
+npm run test:ci
+```
