) -> GetFundsReadPlanExpand description
Build the currency-facing read plan for Trd_GetFunds.
effective_currency is the user-requested currency, or a broker default
derived for Futures/Universal accounts when the user omits it.
lookup_currency is the cache/backend key dimension. Legacy
SingleCurrency accounts keep None only when the user also omitted
currency; when the user explicitly requests a currency, C++ still carries
it into ReqParams_Trd_Assets.enCurrency before QueryAsset, so the
backend refresh/cache key must preserve it.
