fix: skip temperature param for GPT-5 reasoning models

GPT-5/o-series models only support temperature=1 (default).
Sending temperature=0.3 (analytics) or temperature=0 (chart) causes
400 Bad Request: 'Unsupported value: temperature does not support X
with this model. Only the default (1) value is supported.'
Now temperature is omitted for gpt-5/o1/o3/o4 models.
