[FEATURE] improve CLI command name and parameters with consistent naming

for now, there are some naming rules on cli command name
- lower-case: ` list-all`, `add-collab`
- lowercase: `listallocations`, `addcurator`,`encryptionpublickey`
- prefix: `alloc-cancel`,`alloc-fini`
- without prefix: `get`
- fullname: `list-all`
- shortname: `ls-blobbers`

And there are some naming rules on cli command parameters
- lower-case : `rx_pay`,`free_storage`,`read_price`, `write_price`
- lowercase: `remotepath`
- fullname: `allocation`
- shorname: `collabid`,`mcct`

It is better to rename all of them with consistent naming rule.

eg `lower-case with prefix and short name`, only root file system commands should be named without prefix.

for examples:
- `mkdir`, `copy`, `upload`, `download`,`delete`...etc
- `alloc-new`, `alloc-get`, `alloc-update`

该 issue 是关于重命名 CLI 命令和参数以确保一致性。首先检查代码库中现有的命令定义，可能位于 cmd/ 或 main.go 等文件中。理解当前的命名模式以及 Slack 链接中提出的规则。检查是否有需要更新的测试。“Done” 意味着所有命令及其参数都遵循单一、一致的命名约定。
