Show source and risk operations in readable audit

Why: Work-source decomposition, detected risks, human answers, and structure decisions were recorded but absent from the audit timeline.

Evidence: Focused presentation/tree tests, production build, and knip baseline pass.

Impact: Audit filters and rows now include the complete business-operation feed without raw payloads.
