[Behavioral] OpenAI: Default value changed

OpenAI changed the default model for its ImageGenTool from "gpt-image-1" to "gpt-image-2" in its published API specification, affecting every call that omits the model field. The change reaches ImageGenTool objects across 14 OpenAI operations, so code relying on the previous default will now route to the newer model without any code change.
