feat(frontend): 更新 TS 类型定义与 API 服务层，对接后端重构接口

types/api.ts:
- TaskSummary/TaskResponse 新增 is_rework, reject_reason, received_at, completed_at 字段
- 新增 TASK_STATUS 常量 (PENDING/WIP/COMPLETED/REJECTED/ARCHIVED)
- 新增 TaskTransferResponse, TaskRejectPayload, TaskTransferPayload 类型
- ProductScanResponse 新增 current_location_id, task_tree 字段

types/admin.ts:
- ProductResponse 新增 current_location_id 字段

services/taskApi.ts:
- 新增 getTaskTree(serialNumber) — 产品全景任务树
- 新增 receiveTask(taskId) — 确认接收
- 新增 rejectTask(taskId, reason) — 品质驳回
- 新增 transferTask(taskId, assignees, name, note?) — 完工裂变转交
