Cleanup thumbnail after user deletes related image/video resource

Excerpt from Discord:
> Thumbnails. Do they ever get deleted?
They don't get deleted at the moment. It's actually not that straightforward to delete them reliably, as there are multiple ways app can delete files (sync, mount, delete, delete version, delete using S3 API credentials).
We may implement partial deletion in the near future from the app UI, however deletion as a result of mount/sync operation is a long-term goal, as we use internally Rclone which isn't really aware of thumbnails.
