Get history for specific prompt

Deprecated. Use /api/jobs/{job_id} instead — the prompt_id returned by /api/prompt is the same value as job_id. This endpoint is maintained for ComfyUI compatibility but will be removed in a future release; no removal date set.

Retrieve detailed execution history for a specific prompt ID. Returns full history data including complete prompt information.
