test(frontend): fix Geschichte component specs for GeschichteType and JourneyItem model

- GeschichteEditor.svelte.spec.ts: remove docFactory + initialDocuments test;
  rename documentIds test to personIds-only; add familyMember+provisional to
  personFactory (were pre-existing omissions)
- GeschichtenCard.svelte.spec.ts: add type:'STORY', replace documents:[] with
  items:[], change body null→undefined to match Geschichte schema
- GeschichtenCard.svelte.test.ts: add status/type/createdAt/updatedAt to factory;
  cast result as Geschichte to avoid spread-widening type inference
