fix(person): type mention items as PersonSummaryDTO, regenerate api

The dropdown and editor typed /api/persons list items as the full Person
entity. The actual wire shape is PersonSummaryDTO, which until the
previous commit had no date fields - so the life-date subtitle rendered
blank in production while fixtures (built from the entity type) kept the
tests green. Retype items as the summary projection and guard the two
personId consumers against the schema-optional id.
