feat(s2): 投研核心端到端跑通（IC 表 + tears 报告）

- Task 加 raw_result 字段；orchestrator get_raw_result（内存存 FactorReport）
- 路由 /factor/list、/task/{id}/ic-summary、/task/{id}/report/{factor}（query token 给 iframe）
- analyzer cfg=None 时加载 data_platform.yaml（修 API 路径 read_db_daily 崩）
- get_status 返回 error_msg（调试+前端 failed 展示）
- 前端 投研-新建（多因子/多标的/日期）+ 结果页（IC 表 + tears iframe）
- factor 冒烟通过：ma5 → IC 1D/5D/10D 真实数据
