mesh-knowledge: the import keeps every field and takes clauses only from the Decision section's own list, and can repair what it held (hq issue 487)

The import at hq f0892019 lost reconstructed, amended and a research effort's touches, held rests-on only as a
citation, took eight records' clauses from a numbered list inside a ### subsection, and left the 11 records with
no Decision section clause-less with nothing queued. Each is held now; refresh repairs a record only the import
ever wrote, and never one changed since.
