Add filter options for originator, delegator and delegatee
Description
Add new filter options for originator, delegator, and delegatee in the admin view to support both global and space/project-level filtering.
For space/project-level views, ensure that the filtered results are scoped to the current user's access and only include data within the project they manage.
