Marking a lead opt_out via /estagio only wrote outreach_lead_states/
outreach_stage_events and never called addOptOut, so the lead stayed fully
eligible for future campaign sends. Also normalize numero with onlyDigits
in POST/DELETE opt-out routes and in the estagio lookup, matching how every
other number in the app (leads.whatsapp, queue.numero) is stored, so opt-out
comparisons never silently miss due to formatting differences.
