RelayModeImagesEdits, including an image_edit.completed SSE event and assertions
for the expected output-token usage. Preserve the existing image-generation

Add output-token coverage for image edits.
This test sets only RelayModeImagesGenerations. The linked objective also requires image-edit coverage. Add an RelayModeImagesEdits case with an image_edit.completed SSE event. This prevents an edit-specific usage path from returning ImageTokens=0 without detection.

当前 main 已能解析 Images 返回的
output_tokens_details，但normalizeOpenAIUsage没有把它拷到CompletionTokenDetails。计费表达式读img_o时仍为 0，图输出被当成普通 completion 计费，导致少收。本 PR 只补这一处拷贝：当
usage.OutputTokensDetails != nil时，写入usage.CompletionTokenDetails。不改表达式、不改价表、不影响 chat/video 等已走c的路径。📸 运行证明 / Proof of Work
