feat: build from captions.coop/captions-deploy, translation models, relay auto-fill

- images/build.sh builds all three images from one pinned captions-deploy
  commit (submodules pin the captions.coop forks; web/Dockerfile is the UI).
- app: UI image configured by env (landing page, site-config.js), translation
  models downloaded into a volume on start (TRANSLATION_MODELS).
- stt: RELAY_AUTOFILL=source|all|off feeds the capture page's /relay-config.
- Drops the recipe's own nginx.conf and web Dockerfile.
