refactor(admin): split training, control-provenance, iace/verification, training/learner, ControlDetail

All 5 files reduced below 500 LOC (hard cap) by extracting sub-components:

- training/page.tsx: 780→278 LOC — imports existing _components/, adds BlocksSection
- control-provenance/page.tsx: 739→145 LOC — extracts provenance-data.ts, ProvenanceHelpers, LicenseMatrix, SourceRegistry
- iace/[projectId]/verification/page.tsx: 673→164 LOC — extracts VerificationForm, CompleteModal, SuggestEvidenceModal, VerificationTable
- training/learner/page.tsx: 560→216 LOC — extracts AssignmentsList, ContentView, QuizView, CertificatesView
- ControlDetail.tsx: 878→311 LOC — adds ControlSourceCitation, ControlTraceability, ControlRegulatorySection, ControlSimilarControls, ControlReviewActions siblings
