test(dashboard): add partial-failure resilience test + fix i18n Dok. key

- page.server.spec.ts: new test verifies topPersons=[] when that fetch
  rejects, rest of reader data still loads — addresses @Sara concern
- ReaderPersonChips: replaces hardcoded "Dok." with
  dashboard_reader_doc_count_suffix Paraglide key (de/en/es)
  — addresses @Felix suggestion
