Transforms EP API corporate-body data to internal Committee format.
The real EP API returns label as a short abbreviation (e.g. "ENVI") while
prefLabel contains the full multilingual committee name. We therefore
prefer prefLabel → altLabel → label for the display name, and derive
the abbreviation from label (always a short code in real responses) with
notation as a higher-priority override when present.
