feat: transport incidents with truck number support

- DB: trucks table + incidents.truck_id FK + transport enum value
- Validation: transport type requires truck_id
- Create API: validates truck exists/active, persists truck_id
- Report form: truck dropdown shown when type=transport (required)
- Admin: TruckManager CRUD + /api/admin/trucks route
- Detail: trucks join surfaced in incident-detail + detail page query
- Inbox (HSE + supervisor): truck filter, transport in TYPE_OPTIONS,
  fixed stale enum values (dropped dangerous_occurrence/mhe_asset/occupational_disease)
- List: transport label + truck number badge in rows
- i18n: transport + truckLabel/truckPlaceholder in en/ms/zh
