- price_monitor: 完全DB版，不再读写 portfolio.json/watchlist.json - holdings代码从DB读取（SELECT code FROM holdings WHERE is_active=1） - 价格写入DB holdings表 + portfolio_summary + live_prices - 3次重试+指数退避防锁 - server.py: 移除API的JSON回退，DB失败直接返回500 - mofin_db.py: execute_with_retry/commit_with_retry + 15s timeout + busy_timeout - mo_data.py: 已是纯DB模式（无JSON fallback） 这是推进的完全DB化。下一步可删除 data/portfolio.json data/decisions.json data/watchlist.json 等遗留JSON。
