Build out administrative functionality for managing Orgs

[briri]

We need to build the pages to allow users to administer Org information.

The org admin should be able to:

• Add/Update a contact email address
• Add/Update/Remove their logo
• Add/Update/Remove their SSO entityId

The super admin should be able to:

• Create new Orgs
• Perform all of the actions the org admin can do
