Fix poster 42 annotation: creators listed the preprint's authors, not the poster's

42.json credited six authors across five affiliations. The poster prints
three authors and two affiliations. Reddy, Dhillon and Tripathi appear
nowhere on it except inside the References citation of the CarD-T
preprint at the foot of the page (13pt, y=0.91), and three of the five
affiliations (Herbert Wertheim School of Public Health, Moores Cancer
Center, Department of Cellular and Molecular Medicine) appear nowhere in
the poster text at all. The author list had been taken from the paper
rather than the poster.

Three independent sources agree on the correct list. The banner reads
"Jamey O'Neill(1,2), Ludmil Alexandrov(2), Parag Katira(1)" over a
two-entry legend; 42_raw.md transcribes exactly that; and
42_sub-json.json, annotated from the same poster, already records those
three with those affiliations. The annotation guide is explicit that
creators are "as shown on poster" and that the full .json adds
looked-up identifiers (ORCID, ROR, DOI, rights), not extra people.

Restores the three authors in byline order and trims Alexandrov to the
one affiliation his marker points at. Every ORCID, ROR, contact
identifier and other field is preserved untouched; the change is
deletions only. Validates against poster_schema v0.2, and the creators
now match 42_sub-json.json exactly.

This matters beyond one record: 42 is one of the two reference examples
the annotation guide tells annotators to study as a template, so the
error was teaching the wrong convention to every poster annotated after
it.
