Improve UX of Workspace management UI

Problem/Motivation

When visiting /admin/config/workflow/workspaces/manage/{workspace}, there isn't any way to filter/search the items in the workspace. If you are building out a large section and want to filter menu item links to only see the node pages, or find a specific page, we sometimes have to navigate to the 3rd or 4th page. And if we do any operation on any item in the workspace, like move it to another workspace, we always go back to the first result page. This makes it really hard to manage changes.

Steps to reproduce

Proposed resolution

Add column sorts, a filter by content type and a title search input
Make the small change to operation links to send back to the SAME page rather then the first page of the result list.

Remaining tasks

User interface changes

API changes

Data model changes
