chore(web): remove standalone Currencies page (managed via Country FK)

Валюты — закрытый сидируемый список (KZT, USD, EUR, RUB), пользователь
их не создаёт. Currency остаётся в БД как FK для Country и Organization;
GET /api/catalog/currencies продолжает работать для дропдаунов в форме
страны и настройках организации. Отдельная страница в меню избыточна.

- удалена pages/CurrenciesPage.tsx
- из роутера убран /catalog/currencies
- из сайдбара пропал пункт «Валюты», иконка Coins больше не импортируется
