fix(translator): remove unsupported token limit fields for Codex Responses API

Browse Source 
The OpenAI Codex Responses API (chatgpt.com/backend-api/codex/responses)
rejects requests containing max_output_tokens and max_completion_tokens fields,
causing Factory CLI to fail with "Unsupported parameter" errors.

This fix strips these incompatible fields during request translation, allowing
Factory CLI to work properly with CLIProxyAPI when using ChatGPT Plus/Pro OAuth.

Fixes compatibility issue where Factory sends token limit parameters that aren't
supported by the Codex Responses endpoint.
