 * Integration tests for auth permission endpoints.

 * Covers the scenarios previously tested via e2e in:
 *   - auth-permissions.spec.ts (admin permissions, has-permission check)
 *   - auth-permissions.ee.spec.ts (custom role with specific permissions)
 *
 * These test the GET /api/user/permissions route with real database state,
 * validating that admin, member, and custom roles receive correct permissions.
