fix(chain): 修评审 CRITICAL+HIGH — 链网关按 session 重建/日志脱敏/resume 原子化+所有权/死导入

Browse Source 
- CRITICAL #1：链 write/review 节点经 gateway_builder 按节点自建 session 现建网关，
  usage_ledger sink 绑活 session，随节点 commit 持久化；run_chain_job 不再转发请求网关
  （其 session 在 BackgroundTask 跑时已关闭，记账行被静默丢弃）。新增 get_chain_gateway_builder
  缝（仿 digest builder），get_chain_gateway 退化为纯 503 凭据预检。守不变量 #1。
- HIGH #2：chain_runner 失败日志不再记 str(exc)（可能含 key/连接串/LLM 输出），改记
  _classify_job_error 脱敏文案 + exc_type（设计 §5）。
- HIGH #3：resume 端点原子抢占 awaiting→running（JobRepo.claim_awaiting_to_running 条件
  UPDATE），抢不到 → 409，防并发 resume 双 Command(resume) 损坏图。
- HIGH #4：resume 校验 job.project_id == project_id（JobView 新增 project_id），不匹配 → 404。
- HIGH #5：resume 返回新 ChainResumeAccepted{job_id,chain_key}，去掉无意义哨兵 start/count=0。
- HIGH #6：删 nodes.py 死导入 extract_conflicts（import + __all__）。
- 测试 #7：e2e 断言链跑后 usage_ledger 有行（#1 回归守卫）+ chapter_reviews 每章一行；
  新增 claim 原子抢占单测 + resume 跨项目 404 / 并发 409 端点测。
