chore(stammbaum): regenerate TS API types for relationship endpoints

openapi-typescript pulled the Stammbaum schemas: Person now has
familyMember (required), plus PersonNodeDTO, NetworkDTO, RelationshipDTO,
InferredRelationshipDTO, InferredRelationshipWithPersonDTO,
CreateRelationshipRequest, FamilyMemberPatchDTO. Routes:
/api/network, /api/persons/{id}/relationships,
/api/persons/{id}/inferred-relationships,
/api/persons/{aId}/relationship-to/{bId}, and the family-member PATCH.

Test fixtures in PersonMultiSelect, briefwechsel page, and DocumentList
specs gained familyMember: false where they otherwise typed Person
end-to-end. Pre-existing "missing lastName/personType" fixture errors
in DocumentRow.spec are out of scope.

Refs #358.
