fix: prefer product_version only when it contains a space (marketing name)

product_version is used as model only when it contains a space, indicating
a human-readable marketing name (e.g. "ThinkCentre M910x"). Part numbers
like "J26843-409" have no space and are skipped — product_name is used
instead (e.g. "NUC6CAYH" for Intel NUC).
