    Abilities API: Encode empty object results as JSON objects.

    The run endpoint prepared only associative array results for JSON clients, so an empty array returned for an object output schema, such as the `core/settings-get` result when no setting matches, was encoded as `[]` and failed output validation in JSON clients. Prepare every result, including root results, lists, object and `JsonSerializable` results, so empty objects are encoded as `{}` while arrays stay arrays.
    Register the run endpoint with the `data_processing` route option set to `false`, so the `_fields` and `_embed` parameters and response links leave the result unchanged and it follows the ability's output schema whether it is an object, an array, or a scalar value. The REST API client fixture lists the disabled processing for the run endpoint.

    Follow-up to [64311], [64592], [64689].
