test(submit_runtime): P1-05 broker create mock + auto_verify 단위 테스트 5건

`_fetch_many` mock 패턴으로 P0-02 capture 응답 시뮬레이션 추가:
- classify_broker_reject 7개 status_code 분기 enum 매핑 검증
- place_order success path: orderId 존재 시 submit_state=submitted +
  broker_ack 의 broker_order_id/order_no/order_date/is_reserved/http_status
  6필드 보존 (P0-02 SCHD capture 데이터: V56qyv7r/orderNo=3/2026-05-04)
- place_order missing orderId: 200 OK 인데 orderId 부재 → broker_rejected
  + BROKER_REJECTED_UNKNOWN
- place_order RuntimeError timeout: _fetch_many raise → broker_rejected
  + BROKER_REJECTED_TIMEOUT + http_status=0
- auto_verify=True + submitted: runtime.verify_order 1회 호출 +
  verify_snapshot/verification_state 가 place_order 응답.data 에 합쳐짐

helper 신규: _enable_final_submit (env 두 개 set), _stub_place_order_dependencies
(order_preview + _run_prepare_preflight mock + MUTATION_JOURNAL_FILE patch).

test_submit_runtime.py 17 PASS (12→17). 전체 스위트 70 PASS / 1 skipped /
1 무관 fail (bridge_lib.PORT 환경 분리, P1-01부터 일관).
