* feat(nested folders): add CountDashboardsInFolder
This commit adds a new method to the Dashboard service and stores: CountDashboardsInFolder. The command struct takes a folderUID, but the store implementation still depends on the parent folder ID. This is temporary; eventually we will replace all references to FolderIDs (associated with Dashboards) with folder UIDs.
There are some unfortunate additional test changes that were necessary after generating the service & store mocks; it looks like that hasn't been generated since the last change(s).

* agree to disagree with the linter
