Indicate organization team privacy setting

If an organization sets `Teams can be public` to `NO`, the team is correctly made private by the api. However, there is no indication of this setting on the team edit page for teams within that organization. The team privacy setting in the api should be cascaded down through the API and reflected in the UI, with an indicator that this setting has been configured at the organization level.

Inspect the API handling for organization and team privacy settings, then trace how the team edit page receives and displays the team privacy value. The work is done when an organization-level restriction is propagated through the API and the UI indicates that the setting is configured by the organization.
