### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary:
Iceberg eager scans attach an SDK metrics reporter and drain the resulting
scan profile immediately after planning. Streaming batch scans skipped both
steps, so their query profiles showed no Iceberg scan metrics even though the
same files and manifests were planned.
This change attaches the existing reporter to streaming scans and drains it
after the split source closes. Because streaming split generation runs
asynchronously, the query execution summary is captured before dispatch.
Profile-group creation is also serialized so concurrent streaming scan nodes
cannot replace one another's metric groups.
### Release note
Iceberg batch-mode queries now report the same scan metrics as non-batch
queries.
