Task 模型: - 新增 received_at, completed_at, reject_reason, is_rework - 新增 TaskRecord 模型 (remark + images JSON) - 状态常量 PENDING/WIP/COMPLETED/REJECTED/ARCHIVED - 全部时间字段改用北京时间 (get_beijing_time) Product 模型: - order_id → 可选; 新增 external_serial, current_location_id - 新增 material_name/spec_model/category/material_type 快照字段 - 新增 overall_status (备货/生产/测试/维修/在库) 迁移: - b2c3: HEX计数器Sequence + external_serial + order_id nullable - c3d4: material快照4列 - d4e5: overall_status - e5f6: task_records表
