feat: 接入京东联盟订单到数据大盘 (#90)

改了什么：新增京东联盟订单查询客户端、cps_order 京东字段迁移、CPS 对账接口 platform=all/jd、数据大盘京东订单与佣金聚合。
为什么改：数据大盘需要展示京东 CPS 真实订单佣金，不再保持占位。
验证方式：python -m pytest tests\\test_admin_read.py::test_dashboard_overview tests\\test_cps_admin.py::test_jd_reconcile_updates_dashboard -q；本地真实拉取 2026-06-27 京东订单 3 行，页面显示京东有效 1 单/佣金 ¥0.13。
