Add support to edit primary storage IP in UI/API for manual failover/recovery of unaffected instances if primary storage fails

### The required feature described as a wish

[Per this closed issue](https://github.com/apache/cloudstack/discussions/11713) , update API and UI to allow changing the IP address of an existing primary storage pool. This is important for manual failover uses or getting other instances up and running by allowing agents to start with new storage quickly and without modifying the database directly.

該 issue 沒有指定檔案或測試。首先定位現有的 primary-storage API 和 UI 流程，接著追蹤儲存池的 IP 是如何表示與驗證的。完成的標準是：不直接編輯資料庫即可透過 API 和 UI 變更現有 primary storage 集區的 IP，且手動容錯移轉或復原可以使用新的位址。
