Broadened extractYearFromPcatCar after auditing 176 null-year prod pcat
vehicles: the build date sits under "production date" (space) far more often
than "production_date" (underscore), and values come both year-first
(2006/02/27) and day-first (08/03/2016). Match the date key by spelling-agnostic
substring and pull the 4-digit year via regex so parseInt no longer reads the
day. Concrete Year param still wins over build date.
