[UI] Add Object Storage Fails using GET Instead of POST to Backend

### problem

When trying to Add Object Storage, the UI fails because it sends the payload over GET when it expects POST.

I confirmed that the backend works properly when the request is sent using CloudMonkey.

As I've pointed out before, the ACS UI overuses GET, including for operations where sensitive data is passed in the URL. In this case it happens to break the UI, but we should probably review this behavior more holistically.

### versions

Non-Prod deployment of ACS 4.22.0.1
The backend S3-compatible object storage type is MinIO.

### What to do about it?

_No response_

首先追蹤 UI 的 Add Object Storage 請求，並將其方法和 payload 與傳送至後端且可正常運作的 CloudMonkey 請求進行比較。完成標準是 UI 以 POST 傳送該操作，並成功新增 MinIO 物件儲存；連結的 pull request 表示相關工作已在進行中。
