✨(backend) allow masking documents from the list view

Once users have visited a document to which they have access,
they can't remove it from their list view anymore. Several
users reported that this is annoying because a document that
gets a lot of updates keeps popping up at the top of their list
view.

They want to be able to mask the document in a click. We propose
to add a "masked documents" section in the left side bar where the
masked documents can still be found.
