Fix client/vehicle inline creation and labor catalog visibility

- Migration: make clients.phone nullable (was NOT NULL, broke inline create)
- Vehicle createOptionUsing: use Get callback instead of $livewire->data
  to reliably get client_id in the vehicle inline form
- Remove plate->required() on inline vehicle form (not required in DB)
- Rename 'Norme-ore' → 'Catalog manopere'/'Каталог работ' in navigation
  so users can find the labor catalog easily
