feat(iace): Phase 1 — Haftungs-Fixes, Massnahmen-Verkabelung, Explainability Engine

Phase 1A — Haftungs-kritische Fixes:
- SIL/PL-Badges als "Vorab-Einschaetzung" mit Tooltip gekennzeichnet
- Coverage-Disclaimer in CE-Akte, Projekt-Uebersicht und Print-Export
- Norm-Referenzen: 42 Kapitelverweise durch Themen-Deskriptoren ersetzt

Phase 1B — Massnahmen-Verkabelung:
- 16 neue Massnahmen (M201-M216) fuer bisher unabgedeckte Kategorien
  (communication_failure, hmi_error, firmware_corruption, maintenance,
  sensor_fault, mode_confusion)
- Kategorie-Fallback im Initialize-Endpoint: ordnet Massnahmen aus der
  Bibliothek automatisch per HazardCategory zu (max 8 pro Kategorie)
- Total: 225 → 241 Massnahmen, 0 Kategorien ohne Massnahmen

Phase 1C — Explainability Engine:
- MatchReason Struct in PatternMatch (type, tag, met)
- Pattern Engine schreibt fuer jeden Match strukturierte Begruendungen
- Frontend zeigt "Erkannt weil: Komponente X, Energie Y, Kein Ausschluss Z"

Weitere Aenderungen:
- BAuA/OSHA Regulatory Hints: 3 Enrich-Endpoints (per Hazard, per Measure, Batch)
- Dokumente-Tab in IACE-Bibliothek (36.708 Chunks aus Qdrant)
- Varianten-UX: Basis-Projekt-Summary auf Varianten-Seite
- Projekt-Initialisierung: POST /initialize kettet Parse→Komponenten→Patterns→Hazards→Massnahmen→Normen
- 18 pre-existing TS-Fehler gefixt, Route-Konflikt behoben
- Component-Library + Measures-Library Tests aktualisiert

Tests: Go alle bestanden, TS 0 Fehler, Playwright 141+ bestanden
