refactor(admin): split controls, training, control-provenance, iace/verification pages
Each page.tsx exceeded the 500-LOC hard cap. Extracted components and hooks into
colocated _components/ and _hooks/ directories; page.tsx is now a thin orchestrator.
- controls/page.tsx: 944 → 180 LOC; extracted ControlCard, AddControlForm,
LoadingSkeleton, TransitionErrorBanner, StatsCards, FilterBar, RAGPanel into
_components/ and useControlsData, useRAGSuggestions into _hooks/; types into _types.ts
- training/page.tsx: 780 → 288 LOC; extracted ContentTab (inline content generator tab)
into _components/ContentTab.tsx
- control-provenance/page.tsx: 739 → 122 LOC; extracted MarkdownRenderer, UsageBadge,
PermBadge, LicenseMatrix, SourceRegistry into _components/; PROVENANCE_SECTIONS
static data into _data/provenance-sections.ts
- iace/[projectId]/verification/page.tsx: 673 → 196 LOC; extracted StatusBadge,
VerificationForm, CompleteModal, SuggestEvidenceModal, VerificationTable into _components/
Zero behavior changes; logic relocated verbatim.
