feat(p40): 觀測台收官 — 4 頁升 L2 + RAG 根因 + 蒸餾池監控
接續 Phase 39 (commit 79cf08c),本 commit 完成 Phase D 最後 4 項:

D-6: quality_trend 蒸餾池 + RAG 根因
- 新「蒸餾池狀態」card:learning_episodes 各 promotion_status 分布
  (pending / awaiting_review / approved / rejected_quality /
   rejected_hallucination / rejected_duplicate / rejected_human / expired)
- 對最差 3 名 caller (avg_score < 3 且反饋 ≥ 3) 自動 RAG 根因建議
- RAG 從 ai_insights 召回相似低品質案例

D-7: ai_calls 一鍵 Code Review (L2)
- 新 POST /observability/ai_calls/trigger_code_review
  讀 git rev-parse HEAD + diff-tree 取最新變更檔案
  在 daemon thread 跑 CodeReviewPipeline.run() (5 step Hermes→
  OpenClaw→EA→NemoTron)
- 頁面新增「觸發 Code Review Pipeline」按鈕

D-8: ppt_audit 失敗 row 一鍵 AiderHeal (L2)
- 新 POST /observability/ppt_audit/trigger_aider_heal
  接收 pptx_filename + error_msg,呼叫 services/aider_heal_executor::
  execute_code_fix 自動修 services/ppt_generator.py
  AiderHeal 修完會 git push 觸發 CD
- audit_records 表中 status='failed'/'error' 的 row 自動顯示按鈕

D-9: host_health 一鍵 AutoHeal (L2)
- 新 POST /observability/host_health/trigger_autoheal
  接收 host_label,白名單對應 OLLAMA_HOST_PRIMARY/SECONDARY/FALLBACK
  防 SSRF。已標記 unhealthy 的 host 才允許觸發
  呼叫 auto_heal_service.handle_exception(error_type='ollama_unhealthy')
  跑 ADR-013 playbook(DOCKER_RESTART / SSH_CMD / ALERT_ONLY)
- 三主機 row 中 unhealthy / down 的 host 自動顯示按鈕

升級對應:
- AI 自動化:L2 從 1 個 → 4 個(budget force_throttle / Code Review /
  AiderHeal / AutoHeal)
- DB 利用率 ~60%:新增 learning_episodes 分布查詢
- RAG 整合 4/6(promotion_review + budget + quality_trend + 待 ppt_audit)

Phase 38+39+40 累計:6 commits 完成觀測台從 raw dashboard
升級到 AI 自動化專業舞台。
