问题：
- approveTaskItemGroup方法在审核指派子任务时，没有设置claim_time和receiver_name
- grabAssignedItem方法在指定任务接单时，没有更新receiver_name

修复：
- approveTaskItemGroup中增加item.setClaimTime(now)和item.setReceiverName(receiver.getRealName())
- grabAssignedItem SQL增加receiver_name字段更新
- grabAssignedItem方法签名增加receiverName参数

影响：修复后，通过审核指派或指定任务接单的子任务将有完整的接单记录，
确保后续完结任务等流程能正确执行
