feat(HEL-566): 去掉主站行情管理入口并修好模型列表收起

主站行情管理并入数据中枢
- 数据中枢数据源配置页新增「主站行情任务」卡：交易时段后台刷新开关、
  手动后台刷新、历史区间回补（任务提交 + 轮询主站 job 记录亮灯），
  数据与调度仍归主站，控制台只经桥接代操作
- 新增桥接端点 /api/hub-admin/market/{refresh,backfill}；回补改为
  market.backfill 后台任务（jobs.config.json 注册，锁独立，超时 30 分钟），
  桥接调用秒回，不再阻塞
- 主站桌面端删除顶栏「行情管理」按钮与整个行情管理对话框，清理随之
  失效的 CSS；移动端删除 system/admin 页与入口，管理员专区只留数据中枢
- Tushare Token / iFinD 凭证编辑沿用数据源页既有凭证区，无功能缺失

模型池收起修复
- 拉出模型清单后按钮切换为「收起列表」，收起只留一行摘要；再次点击
  重新拉取并展开；勾选添加完成后清单自动收起（原逻辑保留）
- 交互全部沿用 HEL-558 已确认样式的既有按钮与提示组件，未新增视觉

自测
- verify_baseline 通过；pytest 492 项通过；数据中枢 240 项通过
- verify_datahub_console 新增 [11b] 行情任务桥接端到端段；UI 自测新增
  行情任务卡开关往返、模型清单展开/收起/再展开/添加自动收起，日夜主题
  与 1030 窄屏复验通过
- Playwright e2e 102/103：唯一失败项在基线提交上同样失败（本机字体度量
  导致的头部溢出，与本卡无关）
