fix(live): max_pool 全链默认 30→0(0=不限)——08-24巡检定罪MVP限流泄漏生产,选股池=代码序前30只失真 [vps]

根因(策略session 08-24 午休探针实证):runtime/live_strategy.py SANGUO_LIVE_MAX_POOL
默认30经env注入全部实盘+影子+paper实例,_stock_pool截断成份池为「代码序前30只」:
small_cap「全市场最小市值」实际在000001平安银行等30只固定代码里选(平安银行≈3800亿
出现在小市值买入=market_cap开盘NaN排序失效叠bug);momentum每行业RPS只在代码序前
30里排;value 0/30+零委托史同源。注释自曝「MVP验证用」=限流遗留泄漏生产,上线
首日起全部选股失真。

改动(9处默认位一致30→0;语义0=不限,与策略层max_pool>0才截断一致):
- sanguo_portfolio/live_strategy.py 适配器env默认+docstring
- sanguo_live/runner.py _portfolio_env_for(存量DB显式值不篡改,缺列/0→"0")
- sanguo_trader/shadow/supervisor.py 影子env默认
- sanguo_portfolio/runner_live.py live_env默认
- sanguo_trader/portfolio_paper.py + sanguo_api/routes_paper.py paper默认
- sanguo_api/routes_live.py create setdefault
- frontend live/paper New.vue 表单默认

测试:env mapping三态断言(缺列/0→"0",显式30不篡改)+live_env默认"0"
(RED→GREEN);CI范围642绿。存量实例DB仍存显式30,激活需配套DB迁移,必须与数据
session的get_security_info_batch SQL治本(101s→亚秒)同车部署——池放大×慢SQL=更糟。
