feat: document drawer controls (#7679)

## Description

Currently, you cannot create, delete, or duplicate documents within the
document drawer directly. To create a document within a relationship
field, for example, you must first navigate to the parent field and open
the "create new" drawer. Similarly (but worse), to duplicate or delete a
document, you must _navigate to the parent document to perform these
actions_ which is incredibly disruptive to the content editing workflow.
This becomes especially apparent within the relationship field where you
can edit documents inline, but cannot duplicate or delete them. This PR
supports all document-level actions within the document drawer so that
these actions can be performed on-the-fly without navigating away.
