Rename `client_id` field of the `auth-register` command to `delegate_wallet_id`

`client_id` field of the `auth_register` is used in the `DelegateWallet` field of the `add_authorizer` transaction, while `client_key` is used in the `PublicKey` field of the txn. They need to be not in correspondence with one another, since this will mean that the authorizer is trying to self-delegate (i.e. use the same wallet for operations and delegation), which is not allowed.
This field should be renamed to `delegate_wallet_id` to be clear that this will not correspond to the `client_key`.

在代码库中找到 `auth-register` 命令，很可能在 commands 或 cmd 目录中。找到名为 `client_id` 的字段，并将其重命名为 `delegate_wallet_id`。更新命令中以及 `add_authorizer` 交易构建逻辑中的任何相关验证或用法。运行现有测试以确保更改不会破坏功能。
