fix: Lighter stop/take-profit orders must use TimeInForce=0 (ImmediateOrCancel)

Browse Source 
Lighter SDK validates that StopLossOrder (type=2) and TakeProfitOrder (type=4)
must have TimeInForce=0 (ImmediateOrCancel), not TimeInForce=1 (GoodTillTime).

This was causing stop-loss and take-profit orders to fail validation and not
be submitted to Lighter exchange.
