Allocation size issue

Create a 50GB allocation using the newallocation command in zboxcli, then fill all 50GB.
Increase the allocated capacity to 100GB with the updateallocation command and then lock an additional 50GB of ZCN in the write pool.
I uploaded the file, but an error "Max size reached for the allocation with this blobber" appears.

该 issue 涉及 zboxcli 中的 `newallocation` 和 `updateallocation` 命令。首先检查代码库（可能在 cmd/ 目录中）中的命令实现。查找有关分配大小和 blobber 限制的验证逻辑。错误信息 'Max size reached for the allocation with this blobber' 表明在 blobber 交互或分配更新逻辑中存在检查。请在本地复现步骤以理解故障点。
