Alexandre Catarino da1bade3fa Add Interactive Brokers KRX future fees (#9655) ...

KOSPI 200 (KM) futures were added in #9585, but the Interactive Brokers
fee model had no entry for Market.KRX, so its future fee lookup threw
'unexpected future Market krx'. The transaction handler surfaced it as
'Error executing margin models' and invalidated the order before it
reached the brokerage, making every KRX future order fail regardless of
the account permissions or the market state.

IB charges Korea Exchange futures a flat percentage of the trade value
that already includes the exchange, regulatory, clearing and carrying
fees, unlike the per contract fees of the other supported markets, so
the fee is computed from the security price and its contract multiplier
and returned in the contract quote currency.

Also add the KRW currency string and its display symbol.
