Consistent Application of Custom Default Map Layout Across All Device Addition Methods

NetBrain currently does not consistently apply a custom default map layout across all the ways a dynamic map can be created or opened. The layout applies correctly when devices are dragged onto a map from a site, but it does not apply when individual devices are dragged directly onto the map, and it does not automatically apply when a site map is simply opened. This enhancement would allow a custom layout, once set as the default, to apply automatically and consistently regardless of how devices are added or how the map is accessed, without requiring an extra manual step. Ensuring consistent behavior would reduce manual rework and provide a more predictable, reliable map presentation for customers who rely on standardized layouts across their environment.
