View Fileset: Fixity Check button

[eporter23]

When we added the Fixity Check button, we realized there wasn't much room to co-locate it with the current button set.

For this ticket, we want to:

• Identify a better placement for the button
• Restrict visibility of the button so that it only displays to Admin-level users

some options for where the button can go:
i don't think it looks too bad with the buttons at the top

but could also combine the single-use link buttons into a dropdown?

at the end of the card title

below the thumbnail

turn the download and fixity check into an action items menu like on the works page

These are all good options! If it will fit on the top row of buttons that'd be great. Otherwise, let's place it below the thumbnail (but with a bit more top margin between it and the Download link)
