fix(live): 成交时间1970守卫——08-20探针首日实锤9笔traded_at=1970-01-01 00:00:01(QMT原始时间经引擎pd.to_datetime失败形态落epoch),前端『今日成交』按日期过滤全空+账本trade_date失真(当日仓被当历史仓,T+1视图frozen=0);修=_effective_trade_time守卫:年份<2000一律回退当前时刻(归因轮询≤60s,日期误差仅跨日60s窗口);+2测试(1970回退当日记账且frozen生效/有效时间原样保留);附带已治疗VPS存量9行(从引擎日志按标的+数量回填13:03/13:05真实时刻,#18今日成交即时可见);portfolio 29+398绿 [vps]
