Allow admin users to view and manage all workspaces #143
Description
What feature do you want to see added?
Allow admin users to view and manage all workspaces.
Why do you want this feature? Does it solve a problem?
This would allow admin users to have oversight of all workspaces in the platform.
How should the feature be implemented?
It should reuse the existing layouts and views as much as possible, but be clear to the user that they're viewing someone else's workspace.
A separate screen should be used for viewing all workspaces, as opposed to just viewing the ones they can access.
Additional context (if applicable)
This follows on from #128.
