feat(worker-platform): 接单平台全面改用内部统一工单号，隐藏第三方平台单号防泄漏

1. 新增业务工单单号生成器 generateWorkOrderNo()，生成 WO+年月日+时分+随机数的统一内部单号（如 WO26091216358821）；
2. 接单平台抢单大厅、订单列表、详情抽屉、模态弹窗及售后全面切换为展示 workOrderNo，彻底屏蔽拼多多/快手等第三方平台来源标识；
3. 打手资金明细补充关联内部工单号 relatedWorkOrderNo，避免打手在账单中识别原平台；
4. 管理后台工单面板升级为双单号清晰展示（高亮内部工单号 + 辅助可复制平台单号），兼顾打手对单与官方平台售后溯源。
