Modify SL Limit Order not working

[jax248]

Modify order is not working properly in case of STOPLOSS.

• modifyOrder() method only sends a subset of OrderParams fields to the API: quantity, price, ordertype, variety, etc.
• Critical missing fields: triggerprice and stoploss are completely ignored in the modify request.
• User sets orderParams.triggerprice, but the library never includes it in the JSON sent to API.
• The API receives an incomplete request, so the modification fails silently (order stays pending with original values).

Let me know in case any more info is required.
