feat(03-02): catalog page + ServiceTable + ServiceForm + NavBar link

- Create src/app/admin/catalog/page.tsx: server component, fetches all services, renders ServiceForm + ServiceTable
- Create src/components/admin/catalog/ServiceForm.tsx: add-new-service form with open/collapse toggle
- Create src/components/admin/catalog/ServiceTable.tsx: per-row inline edit (DocumentRow pattern), Attivo/Disattivato badges, opacity-50 for inactive
- Modify src/components/admin/NavBar.tsx: add Catalogo link after Statistiche
- TypeScript clean, npm run build compiled successfully
