L3 - Default Context:
See parent task.
AT:
- only users authorized to an event based process can see reports based on the corresponding event based process definition
- only users authorized to an event based process can see and manage collection data source entries of that definition
- extract `addEventProcessDefinitionDtoToElasticsearch` into `ElasticSearchIntegrationTestExtension` as it's used for multiple tests
- all adjacent services use the generic `DefinitionAuthorizationService` to check for definition auth instead of directly calling the `EngineDefinitionAuthorizationService`
- ideally all definition dto's returned from DefinitionReader extend `SimpleDefinitionDto` so the information whether a definition is engine or event based is available without the need of calling the reader again to determine this
