Fix missing files in GigaDB

[rija]

User story

As a curator
I want to efficiently add to the database the missing file detected through audit
So that all data files that we host are included in the database with minimal amount o work

Acceptance criteria

Given I have a list of missing files (from #752)
When I select click on the file
Then the relevant file(s) are added to the correct dataset in GigaDB
And a history log item is added

Additional Info

to investigate:
