Fix: Enable litellm.drop_params for O-series/GPT-5 model compatibility

O-series (o1, o3) and GPT-5 models only support temperature=1.
Setting litellm.drop_params=True auto-drops unsupported parameters
instead of throwing UnsupportedParamsError.

Fixes temperature=0.01 error for these models in LLM extraction.
