🐛 [#1904] Fix Case list crashing due to reused Statustypen

task: https://taiga.maykinmedia.nl/project/open-inwoner/task/1904

if the ZGW APIs reuse StatusTypen for different ZaakTypen, we end up with multiple `ZaakTypeStatusTypeConfig` that have the same `statustype_url`, which led to errors when retrieving these configs. To fix this we explicitly filter for the correct `ZaakTypeConfig` as well
