feat(data): 双源5yr全市场部署 + baostock 15min + 断点续传

- raw_redownload 加断点续传(exists/skip已存在, 扩范围重下覆盖)
- baostock_download: 15min双源(qfq+raw)下载器, NAS容器跑, 限速防封
- full_deploy_5yr.sh: 无人值守日线双源pipeline(qfq→raw→rsync→验证)
- verify_dual_source: 容器内双源部署验证(fetch_day/iter_bars/除权日)

实测: 日线双源5yr 29600文件×2(rsync NAS), 浦发除权日 raw-5.9%/qfq-0.7%,
容器内 fetch_day/iter_bars/全市场抽检5只全通过. 15min沪深300 baostock限流121只.
