The Option 2 migration dropped Gitea's 5c797c8, which added GameCatalog.CATAN
and a Katan entry (available = false: Coming soon on dev, hidden from
production). CatanRules.kt references GameCatalog.CATAN, so the merge did not
compile without it. Taken verbatim from feature/catan-engine, with the
matching CatalogTest assertions.
