Featured publication cards show "Portico" as the publisher #1006

Featured publication cards on the cluster pages show "Portico" as if it were the publisher, for example "Current Protocols, 6(1). Portico. https://doi.org/10.1002/cpz1.70299". On main, 42 lines of data/pub_cards.json contain it.

The text comes from the APA column read by scripts/build_featured_data.py, so the fix belongs in that source or generator. data/pub_cards.json is rebuilt daily, so a hand edit wouldn't last. #984 removes the same artefact from data/clusters_v4.json only.
