[Update] Add Window Title bar.

[bugfix] Note: I think this is tauri's bug. When I try to resize the window and hovered dragable area, I could see resize cursor but it work as a dragging the window behavior that should't be.
Updated npm packages but still not work so I  managed it as adding margin-top by referring Discord title bar.
