The spacing on the navigation tree with dropdowns on MacOS is inconsistent with Windows

The left side navigation tree has editable labels

The selection of first child navigation item is inconsistent on MacOS and Windows, e.g. clicking on "Wind" selects "PV Location and Resource" page under PV

"Hybrid" appears at bottom of technology tree selection on MacOs and under "Energy Storage" on Windows

Based on testing wxWidgets samples, the fix appears to be to replace the wxDataViewTreeCtrl with the wxDataViewCtrl with a custom wxDataViewModel
