User management (Admin section)#222

When I want to see how many users are signed up to my pro plan, or remove or adjust a users permission.
I want to be able to do it in the app.
So I can view the amount of users and make necessary adjustments without contacting support.

Consider if this is a standalone section or is done in the share screen.
(Only invited users are added to the share screen).

Support request from a customer.
One user moved on from our company, we recreated an email with the same name but they could not access the wiki.

Suggested fix:

• Check user id on login, if not, archive user and set up new one.
• Allow deleting users from admin panel

Also requested: allow disabling readers to create their own wikis.
