Security tests for permissions and access control (app/api/dependencies/permissions.py).

Critical security tests covering:
- Inactive user blocking (prevents deactivated accounts from accessing APIs)
- Superuser privilege escalation (auto-OWNER role in organizations)

These tests prevent unauthorized access and privilege escalation.
