Fixes the Harmony streaming function-call completion item to set id instead of passing event-only fields into ResponseFunctionToolCall.

Previously, item_id was stored as an extra field and the real id stayed None, producing id: null in response.output_item.done. This matches the existing emit_simple_tool_call_done pattern.
