📄 Description

Update usage data handling to use 'or {}' instead of default parameter to properly handle None values from API responses.

some api server return data like

data: {"id": "chatcmpl-5jR1Fhd9KUk4P6N3zWo2y4coMscGu", "object": "chat.completion.chunk", "created": 1758113545, "model": "claude-neptune-v3", "choices": [{"index": 0, "delta": {"role": "assistant", "content": "3会更精确。"}, "logprobs": null, "finish_reason": null}], "usage": null, "system_fingerprint": "fp_d576307f90"}

The code usage = data.get("usage", {}) gets None, which causes the open-webui to not display the message correctly.
