Classify every allele-shaped token in HLA report text or model output

Nomenclature checking against the pinned release, not interpretation of a case. Send HLA typing report text or model output about HLA typing with patient identifiers removed first: no names, medical record numbers, dates of birth, accession or case identifiers, or other patient details. The service neither needs nor wants them and does not store request bodies; de-identifying is the caller's responsibility.
