feat(pickup): 新增管理员线下提号功能

- 新建 admin_pickups 表独立于 rental_orders，不污染订单状态机与财务统计口径
- 提号中/已完成/已取消三态：创建锁定账号，完成时给卖家钱包加可用余额并下架 listing，取消解锁账号
- 完成时 listing 置 completed，复用现有 listingLockedForOwnerMutation 拦截再上架
- 管理端提号管理页（列表/创建/完成/取消/可提号账号搜索）+ 卖家端提号记录页
- 财务仪表盘新增线下提号独立统计块，与正常订单口径分离
- 钱包流水 label、状态标签、菜单入口同步补齐
- 优化卖家服务悬浮菜单为一行四个，尺寸与配色对齐买家服务
