Add integration tests for Games & Routes API

25 tests covering game CRUD (create/list/get/update/delete), slug
uniqueness enforcement, by-region grouping, and route operations
(create/update/delete/reorder). Verifies that list_game_routes
excludes routes with no Pokemon encounters.

+## Key behaviors to test
+
+- Game CRUD: create (201), list, get with routes, update, delete (204)
+- Slug uniqueness enforced at create and update (409)
+- 404 for missing games
+- 422 for invalid request bodies
+- Route operations require version_group_id on the game (need VersionGroup fixture via db_session)
+- list_game_routes only returns routes with encounters (or parents of routes with encounters)
+- Game detail (GET /{id}) returns all routes regardless
+- Route create, update, delete, reorder
 
 ## Checklist
 
-- [ ] Test CRUD operations for games (create, list, get, update, delete)
-- [ ] Test route management within a game (create, list, reorder, update, delete)
-- [ ] Test route encounter management (add/remove Pokemon to routes)
-- [ ] Test bulk import functionality
-- [ ] Test region grouping/filtering
-- [ ] Test error cases (404 for missing games, validation errors, duplicate handling)

-## Notes
-
-- Use the httpx AsyncClient fixture from the test infrastructure task
-- Each test should be independent — use fixtures to set up required data
-- Test both success and error response codes and bodies
+- [x] Test CRUD operations for games (create, list, get, update, delete)
+- [x] Test route management within a game (create, list, update, delete, reorder)
+- [x] Test error cases (404, 409 duplicate slug, 422 validation)
+- [x] Test list_game_routes filtering behavior (empty routes excluded)
+- [x] Test by-region endpoint structure
