fix: attach couchdb to coolify external network for Traefik routing

The container was only on the project's default network, so Coolify's
Traefik (on the shared coolify network) had no route to it — Traefik
matched the router but reported "no available server". Putting couchdb
on both networks lets Traefik reach 5984 while leaving the init sidecar
talking to it over the default network as before.
