test(verify-v04): polish — clean W4 final-state + dynamic 미완 section

직전 commit (f31aa5d) 의 두 보고서 결함 수정.  결과 수치 (26/1/0) 동일.

1. W4.json `final=...` 가 OpenRouter 402 응답 JSON 의 중간 문자
   (`'message': 'Insufficient credits. Add more using https://...', '`)
   에서 잘려 보고서 셀이 지저분.  `finalize_w34.py` 가 402 + "credit"
   문자열을 감지하면 `next-phase blocked by OpenRouter 402
   (credit top-up needed)` 한 줄로 치환.

2. `build_report.py` 의 미완 / 후속 작업 섹션이 W3 PASS 인데 phase 4 가
   미완료 라는 nuance 를 놓침 (기존: "없음 — W3/W4/C12 모두 live PASS").
   W3.note 가 "pending" / "credit" / "/4 phases" 패턴을 포함하면 phase 4
   결제 대기 안내를 자동 표시.

3. C12.json / W3.json / W4.json 의 ts 갱신 (재실행 흔적).
