Zoom to Fit, Fit Width, and Fit Height Options for Maps

NetBrain maps currently require users to manually adjust zoom level to view the full topology or a specific dimension of it, with no automated option to fit the visible content to the map window. This enhancement would add Zoom to Fit, Zoom to Fit Width, and Zoom to Fit Height controls, allowing the map view to automatically scale to the available display area. This capability would reduce manual zoom adjustments and improve usability when reviewing maps of varying sizes and layouts.
