feat(swift): implementeer artifact opening from chat (E3.S6) 🎉

Epic 3 Story 6 compleet: Artifacts openen automatisch vanuit chat!
🎉 EPIC 3 COMPLEET - Medical Scribe Chat werkt end-to-end!

E3.S6 - Artifact Opening from Chat (2 SP)
- PendingAction state triggers artifact opening
- useEffect in CommandCenter luistert naar pendingAction
- Automatische block opening met prefill data
- Visual flow: Chat → AI → Action → Artifact verschijnt rechts

Components Updated:
- components/swift/artifacts/artifact-area.tsx (86 regels)
  - Renders DagnotatieBlock, ZoekenBlock, OverdrachtBlock
  - Placeholder state wanneer geen block actief
  - Conditional rendering based on activeBlock state

- components/swift/command-center/command-center.tsx
  - useEffect voor pendingAction handling
  - openBlock(type, prefill) aanroep
  - setPendingAction(null) cleanup
  - Console logging voor debugging

Artifact Opening Flow:
1. User: "Notitie voor Jan: medicatie gegeven"
2. AI response met JSON action (confidence 0.95)
3. ChatPanel: parseActionFromResponse()
4. ChatPanel: setPendingAction(action) if confidence ≥ 0.7
5. CommandCenter: useEffect triggers op pendingAction
6. CommandCenter: openBlock('dagnotitie', { patientName: 'Jan', ... })
7. ArtifactArea: Renders DagnotatieBlock met prefill
8. setPendingAction(null) cleanup

Features:
- Automatische artifact opening bij high confidence (≥0.7)
- Prefill data van AI naar block (patientName, category, content, etc.)
- Console logging voor debugging:
  - "[CommandCenter] Processing pending action: {...}"
  - "[CommandCenter] Opening artifact: dagnotitie with prefill: {...}"
- Placeholder state met voorbeelden wanneer geen artifact actief
- Overflow-y-auto voor scrollable artifacts

Blocks Supported:
- dagnotitie → DagnotatieBlock
- zoeken → ZoekenBlock
- overdracht → OverdrachtBlock
- fallback → FallbackPicker

Build Status:
- ✅ pnpm build succesvol (geen type errors)
- Alleen bekende warnings (Supabase realtime, useCallback)
