mem_limit: 768m causes the kernel cgroup OOM killer to fire before
the Erlang VM writes its first log line on a swap-heavy host — manifests
as exit code 1 / empty docker logs / OOMKilled:false (kernel kill, not
Docker's own cgroup reporter). Removing the limit lets CouchDB start.
Also adds enable_cors = true to [httpd] — required in CouchDB 3.x for
the [cors] section to take effect (without it CORS headers are silently
dropped).
