openclawEntriesToModels() used the agent Name (which may contain
spaces, e.g. "Sub2API OPS") as Model.ID. This ID is passed to
openclaw via --agent, where normalizeAgentId mangles spaces into
hyphens ("sub2api-ops"), causing a lookup miss against the
registered id ("sub2api") and a "no parseable output" error.
Fix: prefer agent ID for Model.ID; use Name only for display Label.
When ID is empty, fall back to Name for backward compatibility.
