Animation Video S3 storage growth is unbounded

[Hamms]

The S3 bucket where we are storing the rendered animations is currently at 130 gigabytes, and growing by a couple hundred megabytes a minute.

It's not particularly necessary for us to store these long-term; the standard workflow is for users to download the videos locally rather than viewing them online, and the videos can always be reconstructed from the logs. Post-HOC, it would probably be worthwhile to set up an automatic purge of videos older than 30 days, and also construct a video download workflow that can regenerate deleted videos.

Additionally, the bucket where we store the logs is at 55 gigabytes; the log format itself is significantly more verbose than it needs to be, and could either be refactored or run through jsonc to mitigate this.
