Replaces StoreApp.latestVersion with latestSupportedVersion + latestAvailableVersion

We now store the latest supported version as a relationship on StoreApp, rather than the latest available version. This allows us to reference the latest supported version in predicates and sort descriptors.

However, we kept the underlying Core Data property name the same to avoid extra migration.
