fix(portfolio): 前端回测MVP链路5处bug(VPS同步/routes命令/max-pool/filter/日期)

Layer1-3 链路验证发现并修复:

1. VPS runner_backtest旧版(tar同步,修 from bullet_trade.core import BacktestEngine ImportError)
2. routes shlex.quote对Windows路径产POSIX单引号cmd不认 -> 手动拼远端命令
3. routes 'set X=Y &&' 尾空格进value致bullet_trade provider名匹配失败 -> 删set(runner自带setdefault)
4. 加 --max-pool 参数(默认前端30)避免HS300+中小综指1258只基本面下载超时
5. filter_st/filter_new对全成分逐只 -> max_pool slice提前到filter前;
   _coerce_datetime加YYYYMMDD解析(原fromisoformat不认miniQMT日期格式)
