fix(enrichment): only accept valid-qualified Enrow emails in work-email

Enrow's finder qualifies each email valid/invalid. The work-email mapOutput
accepted any non-empty email, so an invalid-qualified address could fill the
cell while hosted billing (which only charges on valid) charged zero. Gate the
cell on qualification === 'valid', consistent with billing.
