日K加载提速：adj_factor 覆盖索引 + 冷路径并发 + 热路径进程内缓存直返

- adj_factor 覆盖索引 (ts_code,trade_date) INCLUDE (adj_factor)：根治堆碎片化
  （单股 6516 行散 6516 块，满载时位图堆扫 1.5s+），Index Only Scan ~2ms；
  因子查询全部改 2 列投影，lag() 窗口只取变点（6516→32 行）
- preview 冷路径 2 会话 2 波并发，信息卡合并为 LEFT JOIN LATERAL 一条
- 鉴权会话 60s 进程内缓存（登出/全端登出即时失效），全站请求省 ~80ms
- pvj/chipsj/stocksj/facetsj 存 model_dump_json 原串直返（与 response_model
  字节一致），热路径 230-2190ms → 1-2ms；get_version 本地缓存+bump 即时可见
- 连接池 10+20；smoke_test 适配鉴权缓存
