fix(review): GeschichtenCard uses GeschichteSummary type; focus-visible on journey links; fix stale tests

- GeschichtenCard.svelte: use GeschichteSummary instead of Geschichte
  (list endpoint returns summaries; no items/createdAt/updatedAt needed)
- GeschichtenCard.svelte.test.ts: factory returns GeschichteSummary with
  lean author shape; drop Geschichte-only fields (createdAt, groups, etc.)
- geschichten/[id]/+page.svelte: add focus:outline-none focus-visible:ring-2
  focus-visible:ring-focus-ring to journey item document links (WCAG 2.4.7)
- page.svelte.test.ts ([id]): replace stale documents[] factory field with
  items[]; test now checks placeholder text + note caption
- page.svelte.test.ts (new): remove removed initialDocuments from baseData;
  rename test to reflect that only initialPersons is passed through
