- Update test_invalid_input_types to test actual serialization failure
- Update test_interpolate_only_unsupported_type_error with proper __repr__ method
- Update test_interpolate_invalid_type_validation to test serialization vs rejection
- Update test_interpolate_custom_object_validation to distinguish serializable vs unserializable objects
- All tests now align with new behavior where unsupported types are serialized instead of rejected
