Make it possible to archive fund and labs

[frjo]

This would make list more manageable for organisations that use Hypha for many years.

Form associated with an archived fund or lab should not show when creating a new fund or lab.

@wes-otf There exist a function to "Unpublish" funds and labs. I think we could use that in place of adding a new "Archive".

Unpublished funds and labs and their forms would not show in lists by default. We would add filters for Published/Unpublished.
