Replaces the standalone "Beziehung" badge at the bottom of the
metadata drawer's Personen column with small inline pills attached
to each personCard — sender gets labelFromA, the single receiver
gets labelFromB. Matches docs/specs/stammbaum-doc-badge-spec.html.
Drops the now-unused RelationshipBadge component.
