refactor(countries): drop SortOrder, sort by Name, auto-width columns

- Country.SortOrder удалено из домена/DTO/API/seeder/web/UI.
- Миграция Phase5b_DropCountrySortOrder дропает колонку.
- Список стран сортируется по Name ASC.
- В форме: поле «Порядок» убрано.
- В таблице: убрана колонка «Порядок», ширины колонок сжаты по
  содержимому (Код 80px, Валюта 120px, НДС 100px, Название flex).
