Lock Map Layout in Function Portal View

NetBrain currently allows a locked map to prevent device repositioning within the full administrative client, but this lock state is not enforced when the same map is opened through the Function Portal, allowing viewers to move devices individually and alter the shared layout. This enhancement would extend the map lock setting to the Function Portal so that a locked map remains non-editable for all viewers, regardless of access method. Enforcing consistent lock behavior across both interfaces would preserve intended map layouts and prevent unintended changes when maps are shared with external or internal viewers.
