feat(forms): MoneyInput/NumberInput + select-пагинация + Range на бэкенде

UI:
- Pagination: ввод страницы заменён на select (option 1..totalPages),
  по выбору сразу setPage. Стрелки ← → остаются.
- Field.tsx: добавлены MoneyInput (decimal + суффикс ₸/$/€) и
  NumberInput (decimal без валюты). Оба фильтруют ввод регулярно
  (только цифры + точка/запятая→точка), при focus — выделяют значение.
- ProductEditPage: purchasePrice / vat / minStock / maxStock / amount
  в ценах продаж переведены на новые компоненты; символ валюты —
  из выбранной валюты позиции/закупки или из defaultCurrencySymbol орг.
- SupplyEditPage / RetailSaleEditPage: quantity/unitPrice/discount
  в строках, paidCash/paidCard в шапке — на NumberInput/MoneyInput
  с символом из form.currencyId.
- CountriesPage: vatRate — NumberInput.

API:
- ProductInput / ProductPriceInput / SupplyLineInput /
  RetailSaleLineInput / RetailSaleInput — добавлены [Range(0,1e10)]
  на денежные/количественные поля и [Range(0,100)] на проценты.
  ASP.NET автоматически валидирует и возвращает 400 при выходе.
