Comments not working on unassigned documents

Why

Comments are essential for collaboration and document review workflow. The feature has regressed and is currently not functioning, which impacted a client demo.

What

Fix the comments functionality on documents so users can add, view, and interact with comments as expected.

How

Investigate why comments have stopped working on documents and restore full functionality. Note that COR-795 previously addressed a similar issue and was marked as resolved.

Dependencies

Acceptance Criteria
