ReferenceSnapshotInputDto
Client-supplied denormalized display data of a referenced entity — the shape a reference
picker already sends inline on a regular reference field value
({ "id": "...", "snapshot": { "label": "...", "subLabel": "..." } }), lifted out as
its own input for routes that seed the reference server side (BER-1928: the CRM related
detail create) and therefore cannot accept it inline on the field value itself.

"label": "string",
"subLabel": "string"
