Data Model
Summary: This should require a big confirm button, obviously, and only be available to Owner.
I should be able to delete an Archived Space as well, probably from the Archived Spaces page.
Conceivably, we might require archive-then-delete, so that Archive is sort of like a Recycle Bin. But that's likely a hassle for users.
