[fix](regression) Avoid host port hairpin for Fluss MinIO (#69004)
Problem Summary: Fluss containers used the host-published MinIO endpoint
for lake initialization. That same-bridge hairpin path is not available
consistently across Docker networking setups, so the coordinator can
fail before the external regression starts. Use the MinIO service name
on the compose network while Doris continues to use the published host
endpoint supplied by the regression catalog properties.
