The enterprise profile installs qbit-object-storage when S3_ENDPOINT is
set, so collaboration attachments work. enterprise-server.sh now starts
qqq-enterprise-minio on 127.0.0.1:9310 alongside Redis and OpenSearch,
creates the attachments bucket, and passes S3_* to the server. The
credentials are generated once into $TMPDIR/qqq-enterprise-minio.env (0600;
QQQ_ENTERPRISE_MINIO_ENV overrides) and never written to the repository.
container_up takes a container command after "--".
