fix(report): remove redundant before-calling screenshot (#2512)

The before-calling screenshot in the report detail panel is derived from task.uiContext.screenshot.

It is the same image as UI Context, not a separately captured recorder snapshot.

The TaskRunner can also reuse UI Context within its 300ms cache window.

That makes the before-calling label ambiguous, so keep UI Context and remove the duplicate image.
