urgent Fix.: retry once until gen video availability

[jeffmac-aix]

Urgent Fix, for video only: a video generation model might send an URL too early, i.e. before the video is actually generated and available. This causes the overall video generation process to fail. Here we fix this by checking the actual presence of the video file after we get an URL back from video generation API. If not we wait for a 5s delay (this can be changed by changing MEDIA_POLLING_INTERVAL env var) and check again If the URL is find, all good, otherwise we simply log an error and let the flow continue to generate the other videos. We take the assumption that this case is very unlikely to happen until we fix the video availability issue by polling the API properly, which depends on the API / platform, or use webhooks.
