fix(remotemanage): group dialog obscured by terminal window

GroupConfigOptDlg was created without parent and window modality,
causing it to be hidden behind terminal. Now passes parent and sets
Qt::WindowModal, matching ServerConfigOptDlg behavior.

添加分组对话框未设置父窗口和窗口模态，导致被终端窗口遮挡。
现在传入父窗口并设置Qt::WindowModal，与添加服务器对话框一致。

Log: 修复添加分组对话框被终端窗口遮挡的问题
PMS: BUG-358805
Influence: 修复后添加分组对话框始终保持在终端窗口之上，不会被遮挡。
