Update Global Permissions for New Sites

Put Simply: Remove the “Create Team Managed” permission from global settings for all new sites.

Why it Matters: Prevents unapproved project types from being created, improving governance and platform consistency.

Additional Context: No current API available for this; may require investigation into automation or manual process until resolved.

Acceptance Criteria: Any new site should have “Create Team Managed” disabled in global permissions.
