We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Viewing of "file"-kind of CIV in archive items leads to 403
I created an archive item and added a file type CIV but when trying to view the file it leads to a permission denied error. It seems that the permission check when serving a CIV file is missing a check for archive item viewing. It only checks for algorithm jobs and evaluations:

https://github.com/comic/grand-challenge.org/blob/9322d09c0859998a77accb5c13d6db675504a9c1/app/grandchallenge/serving/views.py#L94-L117

Permissions for archives are only done on archive level (vs. archive item level) so we need to add a check here to see if the CIV belongs to an archive item and if the user has the `archives.view_archive` permission for that archive.
