- ExportBackup command: JSON per-table backup with chunk processing
- UserResource: CRUD users with role assignment (admin only)
- RoleResource: CRUD roles with permission assignment (admin only)
- UserPolicy + RolePolicy: admin-only access control
- ImportCskh: detailed skip logging with color in dry-run mode
