refactor(currencies): убрать IsActive и MinorUnit из UI/API

- Currency.IsActive удалён полностью (domain/DTO/API/web/миграция).
  Валюты — глобальный справочник; «архивировать» USD глобально
  бессмысленно, а per-tenant видимости у валют нет.
- MinorUnit остаётся в БД (нужен для форматирования цен), но скрыт
  из UI: убран CurrencyDto.MinorUnit, CurrencyInput.MinorUnit,
  колонка «Знаки» из списка.
- Форма валюты — 3 поля: Код / Название / Символ.
- Миграция Phase5e_DropCurrencyIsActive дропает колонку.
