feat(labors): trilingual name — add name_en column + Labor::label() helper

- Migration: add nullable `labors.name_en` alongside existing name_ro/
  name_ru.
- Labor model: label(?locale) accessor returns name_{locale} with
  name_ro fallback.
- LaborResource form: expose 3rd 'Nume (EN)' field.
- Table + Select displays now go through label() so options show the
  locale-appropriate name:
    /app/labors table column,
    WorkOrderResource works Select ('[category] name (Nh)'),
    ServiceTemplate items Select,
    ServiceComposer WorkOrderWork snapshot on create.
- Snapshot name saved on wo_works.name at creation reflects the
  current locale; existing rows keep their stored snapshot untouched.

All 306 tests pass.
