feat: add hashcode deduplication config for IriusRisk parser

Register IriusRisk Threats Scan in HASHCODE_FIELDS_PER_SCANNER and
DEDUPLICATION_ALGORITHM_PER_PARSER so deduplication uses title and
component_name rather than the legacy algorithm. These stable fields
ensure reimports match existing findings even when risk levels or
countermeasure progress change between scans. Update docs to match.
