Payload.mp4 when downloading files is confusing clients a lot

Hey there,

When using Review ( or generally looking at reviewables and wanting to retrieve the original reviewable ) we need clients ( not logged in guests, this is already shielded correctly ) to be able to fetch the reviewables from the viewport. This currently works, BUT the file is renamed to a generic payload.mp4. Causing a mess. I want to suggest to keep the original name of the uploaded reviewable here, so our own naming keeps things sensible/tidy. I'd say this is quite essential for a clean workflow

Thanks :)
