feat(overdracht): E2 + E3 - API overdracht en dagregistratie UI

Epic 2 - API Overdracht:
- GET /api/overdracht/patients (patiënten met alerts)
- GET /api/overdracht/[patientId] (detail met vitals, reports, logs, risks)
- POST /api/overdracht/generate (AI samenvatting met bronverwijzingen)
- lib/ai/overdracht-prompt.ts (system + user prompt)
- lib/types/overdracht.ts (TypeScript types)

Epic 3 - Dagregistratie UI:
- /epd/dagregistratie/[patientId] pagina
- Quick entry form (categorie, tijd, tekst, overdracht checkbox)
- Edit/Delete functionaliteit met inline editing
- Confirm delete dialog
- Summary cards (totaal, overdracht, incidenten)

Bouwplan bijgewerkt naar v1.2 (10/19 stories voltooid)
