Rewrite /persons: server-side filter chips (type, family-only, has-documents)
that AND within the clean reader default (familyMember OR documentCount > 0),
a writer-only show-all/Zu-prüfen toggle, and reused Pagination. Extract
PersonCard (fixes the null-lastName render crash and never shows a "?" initial —
provisional/UNKNOWN/"?" entries get a neutral placeholder avatar + a text+icon
"unbestätigt" badge, WCAG 1.4.1) and PersonFilterBar (44px aria-pressed chips,
role=switch toggle with the count in its accessible name). The loader applies
the reader restriction unless review=1 and surfaces a cheap needsReviewCount.
i18n keys added for de/en/es.
