Change CouchDB ingress hostname from communicore.mk-labs.cloud to
communicore.local.mk-labs.cloud to align with External-DNS configuration.
CouchDB is an internal service and should use the .local.mk-labs.cloud
zone managed by Technitium DNS, not the public .mk-labs.cloud zone
managed by Cloudflare.
This ensures External-DNS will properly create the A record in the
internal DNS server.
