exported from $lib/relationshipLabels.ts. Adds two direction-sensitive
tests proving the Elternteil-von / Kind-von branch is covered.

A spouse listed as a direct PersonRelationship was also being
emitted as an inferred SPOUSE chip below, so the same person
appeared twice in the Beziehungen card.
Filter the inferred list against the IDs already shown as direct
edges before slicing the top 5. Added a component test that
renders red without the filter and green with it.
