fix(aiops): ADR-072 P1 Bug 修復 — BUG-004/005/006

BUG-004 KM vectorization 108/112 = False:
  km_conversion_service: KM entry 建立後（embedding 已背景觸發），
  補寫 incidents.vectorized = True，飛輪閉環（ADR-068）學習指標正常

BUG-005 15 ready decisions 無人審核:
  decision_manager: 新增 resend_stale_ready_tokens()，
  掃描 Redis decision:* key，找出 state=ready 且 dedup_key 過期的 token，
  重新推送 Telegram 審核卡片
  main.py: lifespan startup 排程 resend_stale_ready_tokens()（asyncio.create_task 非阻塞）

BUG-006 outcome/verification_result 全 null:
  _push_auto_repair_result: Telegram 推送前先寫入
  incidents.outcome + incidents.verification_result 到 DB
