Allow for Contact and Contact List Restriction for IdP-Managed Teammate Groups via the API

If a teammate group's membership is managed by an IdP (Entra, Okta, etc.), the teammate group cannot be edited in Front via the API. This behavior prevents Admin from controlling a teammate group's contacts and contact list access. To control the contact access, Admin need to temporarily disable the teammate group sync, update the contact access, and then re-enable the sync.
