This pull request introduces a workaround for a Dart SDK issue in two Cupertino checkbox test files by invoking copyWith on OutlinedBorder instances derived from ShapeBorder.lerp. This ensures that Type Flow Analysis infers nullable parameters correctly to prevent dart2wasm miscompilation. There are no review comments, and I have no additional feedback to provide.

Follow-up to #12956 to unblock the Flutter-to-packages roller (#12904).
#12956 resolved the dart2wasm hang in packages/cupertino_ui/test/. Previously, CI never reached packages/cupertino_ui/example because the shard timed out while running packages/cupertino_ui.
Now that packages/cupertino_ui passes, CI runs a separate flutter test --platform=chrome --wasm invocation for packages/cupertino_ui/example. Because the example suite compiles into its own standalone Wasm bundle that includes both CupertinoSheet (RoundedSuperellipseBorder) and CupertinoCheckbox, it hits the same dart2wasm optional parameter inference bug in _CheckboxPainter._drawBox when running test/checkbox/cupertino_checkbox.snippet.0_test.dart.
Adds the same OutlinedBorder.copyWith() workaround to cupertino_checkbox.snippet.0_test.dart and cupertino_checkbox.0_test.dart so the example Wasm bundle also keeps the circularity and eccentricity selector parameters nullable.
