"""
Tests for moving teams to organizations.

Covers the SSO/Entra scenario where:
- Proxy admins can move teams freely; missing members are auto-added to the org.
- Non-proxy-admins (team admins) must have all team members pre-added to the org,
  preserving the original security model (no privilege escalation via team move).
