Expand buildRiskAssessmentNotes to persist most of the extracted
assessment (classification, per-category risk breakdown, privacy and
data processing practices, AI governance, contractual clauses,
professional standing, and baseline failures) instead of only a short
summary. Fields already stored as structured columns on the third party
(certifications, data locations, document URLs) are omitted to avoid
duplication.
