feat(iace): Phase 5+6 — frontend integration, RAG library search, comprehensive tests

Phase 5 — Frontend Integration:
- components/page.tsx: ComponentLibraryModal with 120 components + 20 energy sources
- hazards/page.tsx: AutoSuggestPanel with 3-column pattern matching review
- mitigations/page.tsx: SuggestMeasuresModal per hazard with 3-level grouping
- verification/page.tsx: SuggestEvidenceModal per mitigation with evidence types

Phase 6 — RAG Library Search:
- Added bp_iace_libraries to AllowedCollections whitelist in rag_handlers.go
- SearchLibrary endpoint: POST /iace/library-search (semantic search across libraries)
- EnrichTechFileSection endpoint: POST /projects/:id/tech-file/:section/enrich
- Created ingest-iace-libraries.sh ingestion script for Qdrant collection

Tests (123 passing):
- tag_taxonomy_test.go: 8 tests for taxonomy entries, domains, essential tags
- controls_library_test.go: 7 tests for measures, reduction types, subtypes
- integration_test.go: 7 integration tests for full match flow and library consistency
- Extended tag_resolver_test.go: 9 new tests for FindByTags and cross-category resolution

Documentation:
- Updated iace.md with Hazard-Matching-Engine, RAG enrichment, and new DB tables
