Summary: This PR introduces OpenAPI evaluation endpoints and supporting domain changes. I found two critical must-fix issues that will break the flow:

1. Handler ReportEvalTargetInvokeResult does not invoke the service and returns an empty response, dropping incoming results.
2. DatasetRPCAdapter.BatchUpdateDatasetItems is unimplemented and panics, causing BatchUpdateEvaluationSetItemsOApi to crash.

Additionally, there are should-fix improvements: guard against nil in ReportEvalTargetInvokeResult_ when computing latency, and avoid logging full payloads; also fix a misleading error message and a minor IDL comment typo. See inline comments for exact locations and suggested fixes.
