feat(factor): run_eval CLI暴露--fund-data-dir——容器财务批可传静态域(WP1-3收尾补工) [nas]

- --fund-data-dir default=None 透传 batch_eval;默认语义已有三层fallback:
  参数 → cfg.data_paths['static_dir'] → /volume1/stock/sanguo_vnpy_v2/data/static
  (None≠不join,CLI不传参容器内外同路径可跑财务批;量价批不含fundamental因子零开销)
- docstring补财务批用法示例(--categories fundamental)
- 验证: pytest tests/factor/ -x -q 145绿; --list-factors fundamental 列出32个
