Neighbor Window Indicator for Devices On Map but Not Linked

NetBrain currently shows an icon in the Neighbors window only when a neighbor device is both on the map and linked, with no way to distinguish neighbors that are already on the map but not yet linked. This enhancement would add a distinct indicator for neighbors that are present on the map but lack a link, alongside the existing on-map-and-linked icon. Customers building maps through Auto Link or manual expansion of the Neighbors window would be able to quickly identify which on-map devices still require linking, reducing the manual effort needed to complete topology connections.
