feat(persons): redesign detail page sections to match Concept A spec

- CoCorrespondentsList: white card wrapper with navy initials circles in chips
- PersonDocumentList: flat row-divider pattern with variant-tinted icons (sent=navy, received=teal)
- Add variant prop (sent/received) to PersonDocumentList and wire up in page
- Add person_correspondents_hint i18n key to all three message files
