feat: /api/v1/auto-repair/history endpoint + neural-command 接真實 API (Sprint 3)

- 新增 RepairHistoryItem/RepairHistoryResponse Pydantic models
- GET /api/v1/auto-repair/history?limit=N 從 incidents working memory 推導修復歷史
- 前端 fetchData() 同時拉 history + approvals/pending，移除硬編碼 pendingApprovals=0
- try/except 包覆確保任何錯誤都回傳空列表不中斷前端
