Recover native previews, audio loads, and recreated video keyframes
Recover native previews, audio loads, and recreated video keyframes Native previews can remain broken after a transient download error, and recreating a video can silently change how its images are submitted. This fixes five independent state/lifetime defects from #2271: - Recreated prompts restore keyframe versus reference mode from their saved semantics and place explicit start/end frames correctly regardless of list order. - Failed still/animated image previews become retryable after a five-second cooldown, with repaint scheduling. - Failed audio waveforms use the same cooldown instead of remaining permanently failed. - Audio downloads carry a request iden
