[RFE] Add option to disable RDP authentication for Remote Login in gnome-remote-desktop

Issue

• The Remote Login feature for Gnome requires two separate authentications: one for the gnome-remote-desktop service and a second at the GDM login screen.
• This initial RDP service authentication is mandatory and cannot be disabled.
• In secure network environments, where access is already controlled by firewalls or VPNs, the initial authentication gate can be redundant. Can this be disabled?
