feat(worker-platform): 实现打手寄卖白名单权限控制与存量发布打手平滑过渡

1. 新增数据库迁移 082_worker_consignment_whitelist.sql，worker_users 表增加 can_consign 与 consignment_activated_at 字段，存量在 consignment_submissions 提报过的打手默认自动开启；
2. 打手端提报接口 publishWorkerConsignment 增加白名单权限服务端强校验拦截（403 consignment_permission_required）；
3. 管理后台打手管理表格增加「寄卖权限」实时 Switch 开关列与打手详情抽屉权限展示，支持客服即时开通或关闭打手寄卖权限；
4. 打手端我要寄卖页面在未开通权限时展示专属白名单引导卡片，一键呼起联系客服开通寄卖弹窗；
5. 补充寄卖权限拦截与路由单测，前端59项单测与后端507项单测全部通过。
