* fix(dashboard version service): add DashboardUID to query and responses
The DashboardUID was not populated in the response from Get and ListDashboardVersions. This adds the DashboardUID to the Get query (it was already in List) and populated the DashboardUID in the returned DashboardVersionDTOs.
The DashboardVersion struct is the database object; the DashboardVersionDTO is the object that should be sent to the API layer.
In the future I'd like to move DashboardVersion to dashverimpl and un-export it, but there are a few places that Insert directly into that table, not all of which are test fixtures, so that should wait until we clean up at least the DashboardService's use of it.
