price_monitor 汇总值重算 + total_assets修正

问题：price_monitor每2分钟更新个股价，但不更新
total_market_value/total_assets/cash/position_pct，
这些字段停留在import_holding_xls快照值，已严重过期。
导致报告显示错误的总资产和仓位。

修复：
- 每次更新个股价后，实时重算 total_market_value = sum(shares*price)
- cash 从 stale_report（Dad截图确认的可用现金）同步
- total_assets = market_value + available_cash + freeze
- 避免价格无变化时不触发更新（timeout fallback保留）
