Insert a Person

Creates a new person relation in Bloxs.

A developer calls this endpoint to register a new individual (for example a tenant, contact, or other relation type not yet in the system) rather than update an existing one. On success, Bloxs generates and returns the internal reference and display name for the new record, along with the full stored data.
