test: add tests for draft persistence, model status, and model re-entry

10 new tests covering:
- _save_draft / _load_draft / _delete_draft / _mark_step_done helpers
- draft file permissions (chmod 600)
- _show_local_model_status with zero, one, and multiple loaded models
- _test_connection change_model path (model error → change → retry succeeds)
