NestedFolders: Show Dashboard and Folder full breadcrumb hierarchy (#68308)

* update FolderDTO to match backend struct

* hacky way to get folder page breadcrumbs working

* hacky way to get dashboard nested breadcrumbs working

* undo route changes, get url from folder

* fix breadcrumbs in dashboard settings

* add parent pages to navIndex

* adjust getRootSectionForNode to just return the parent of a leaf node

* undo changes to generated files

* undo changes to toggles_gen.go

* feature toggle dashboardInit code

* remove unnecessary code in home dashboard

* build navModel directly, don't use getNavModel

* don't need fallback here

* remove getLoadingNav since it's not used anymore

* don't need to hide tabs from breadcrumbs anymore

* use id to find dashboards tab
