Kalshi 永久 - LIMIT 和 LIMIT MAKER 关闭命令可以打开一个位置而不是减少一个位置

Describe the bug A take-profit order meant only to reduce an open position was accepted by Kalshi as an ordinary opening order. Hummingbot marks it CLOSE internally, but the request carries no reduce-only flag, so Kalshi treats it like any other order.
