Add multilingual support to labor categories (RO/RU/EN)

- Migration: adds name_ro, name_ru, name_en columns; copies name→name_ro;
  seeds RU and EN translations for all 11 default categories
- LaborCategory: label() returns localized name, optionsForSelect() keyed
  by canonical name (stored in labors.category) with localized label
- LaborCategoryResource: 3-column form with RO/RU/EN inputs; table shows
  all three columns side by side
- LaborResource: category select and filter use optionsForSelect()
