beabigegg 3234c7088a feat: 導入 Redis 快取層與 Worker 穩定性強化
- 新增 Redis 表級快取機制,減少 Oracle 查詢負載
- 實作 CacheUpdater 背景任務,每 10 分鐘檢查 SYS_DATE 並更新快取
- 所有 WIP API 端點改為 cache-first + Oracle fallback 架構
- 新增 /health 端點顯示資料庫、Redis、快取狀態
- 前端 Portal 新增即時健康狀態指示器
- SQLAlchemy 連線設置 call_timeout=55s 防止 Worker 卡死
- Gunicorn 加入 max_requests=1000 確保 Worker 定期重啟
- 完整測試覆蓋:67 項單元/整合/E2E 測試
