/**
* Calculates the max allowed network fee for a Yield Supply transaction.
*
* Result is a Pair<BigDecimal, BigDecimal> where:
* - first: fee in native coin units (maxFeeNative)
* - second: the same fee converted to token units using the fiat-rate ratio
* (nativeFiatRate / tokenFiatRate).
* Returns [Either] of [YieldSupplyMaxFee] with:
* - nativeMaxFee: fee in native coin units
* - tokenMaxFee: fee converted to token units using the native/token rate ratio
* - tokenFiatMaxFee: fee value in fiat
*
* Uses YieldMarketToken.maxFeeNative and the same conversion logic as
* [YieldSupplyGetCurrentFeeUseCase].
