Cannot change SL/TP trigger type on conditional orders via API.

[iam-D1]

When placing a conditional order with attached SL:

stopLoss.triggerPriceType set to MARK
Sent via Python SDK (CreateOrderTpslTriggerModel)

Result:

Order created
SL trigger defaults to LAST
MARK not respected

Same behavior as UI:

Conditional order with SL
Trigger type cannot be changed after position opens
