Sprint 2: Live data, CRUD modals, commitments, document upload

Frontend:
- Connect MetroMap to live Inertia props (replace hardcoded demo data)
- Drill-down navigation via router.visit for project-level maps
- Reactive breadcrumb based on map level
- Empty state when no projects exist
- Reusable Modal component with retro styling
- ProjectForm and CommitmentForm with Inertia useForm
- FormInput reusable component (text, date, textarea, select)
- FloatingActions FAB button for creating projects/themes

Backend:
- CommitmentService + CommitmentController (CRUD, mark complete, overdue)
- DocumentService + DocumentController (upload, download, delete)
- MapController now passes users and speerpunten to frontend
- 7 new routes (4 commitment, 3 document)
