Add a meilisearch service to the dev docker-compose (port 7700, persistent volume)
and MEILI_URL/MEILI_KEY (+ IIOS_CRED_KEY, IIOS_MEDIA_GC_INTERVAL_MS) to .env.example.
Add deploy/meilisearch.yaml — a ready-to-apply k8s Deployment/Service/PVC/Secret for
the ArgoCD prod stack (copy into k8s-pods/services/iios/), with wiring notes for the
iios-service env (MEILI_URL=http://meilisearch:7700, MEILI_KEY from the secret).
