feat: add openapi schema and apply configurations

- Add OpenAPI schema generation for zalando.org/v1 API types - Generate apply configurations for client-side apply operations - Create models-schema tool for extracting OpenAPI definitions - Update code generation scripts to support applyconfiguration-gen - Add +k8s:openapi-gen=true annotations to API packages - Enhance client interfaces with Apply and ApplyStatus methods - Update fake clients to support field management - Modernize test clients with new NewClientset constructors This enables server-side apply functionality and improves API discoverability through proper OpenAPI schema definitions for ScalingSchedule and ClusterScalingSchedule resources.

 For this case you should also account for the average time for processing an
 event when defining the target.

+Alternative to defining `subscription-id` you can also filter based on

+This is useful in dynamic environments where the subscription ID might not be
+known before deployment time (e.g. because it's created by the same deployment).
