fix(api): Decimal-параметр ребалансировки ломал генерацию Dart-клиента

cash_available был bare Decimal | None в Query(...) — pydantic отдаёт для
Decimal anyOf[number, pattern-string], который openapi-generator не умеет
свернуть в один тип и вместо этого синтезирует пустой класс CashAvailable
без полей (синтаксически битый .dart, компиляция всего пакета падает).
Остальные Decimal-поля в API давно оборачиваются в Money/MoneyOpt
(api/schemas/common.py) ровно за счёт этого — anyOf[string, null] генератор
понимает. cash_available обошёл соглашение, потому что это единственный
Decimal-параметр запроса во всём API, а не тело ответа.
