The real manual-send route (routes/outreach.mjs) always inserts with
produto='' and lead_id=NULL, so the old single NOT EXISTS predicate
(produto = ? AND (lead_id = leads.id OR numero = leads.whatsapp)) could
never match a real manual send's row -- the numero branch was unreachable
in production even though a prior test fabricated a produto value manual
sends never write. Split into two NOT EXISTS clauses: one scoped to
produto+lead_id (automatic/campaign sends), one scoped to numero+
origem='manual' with no produto requirement (manual sends). Updated the
existing regression test to insert the row exactly like the real route
does (produto: '', lead_id: NULL, origem: 'manual').
