Code Review

This pull request adds support for donation campaigns, nonprofits, and related settings to the Adyen Management API client, introducing several new models, JSON converters, and a new service. Feedback on the changes identifies a runtime fragility issue in ScheduleTerminalActionsRequestActionDetails.cs where jsonSerializerOptions.GetConverter should be used instead of Converters.First. Additionally, missing Models. namespace prefixes in ClientUtils.cs should be added for consistency, and the properties PresentCardTimeoutMs and PromptTimeoutMs in InPersonDonationSettingsUpdate.cs should be corrected from Object? to long? to maintain type safety.

Using jsonSerializerOptions.Converters.First(...) to retrieve the converter is highly fragile and will throw an InvalidOperationException at runtime if the converter is not explicitly registered in the Converters list (for example, when using custom or default JsonSerializerOptions in ASP.NET Core).

Since the models are decorated with [JsonConverter(typeof(...))], the standard and robust way to retrieve the converter is using jsonSerializerOptions.GetConverter(Type). This built-in method correctly resolves converters from all sources (explicit list, attributes, and built-in defaults) without throwing exceptions.

The return statement is missing the Models. prefix, which is inconsistent with the rest of the file (e.g., Models.AndroidApp.StatusEnum.ToJsonValue on line 132). If the Adyen.Management.Models namespace is not fully imported, this will also cause a compilation error. Please add the Models. prefix for consistency and safety.

            if (obj is Models.CampaignStatusTransition campaignStatusTransition)
                return Models.CampaignStatusTransition.ToJsonValue(campaignStatusTransition);

The properties PresentCardTimeoutMs and PromptTimeoutMs are generated with the type Object? instead of long? (or int?). This is inconsistent with InPersonDonationSettings.cs where they are correctly typed as long?, and it breaks type safety for users configuring these timeouts. Please update their types to long? (and update the corresponding JSON converter methods in this file).
