Confirm a managed double opt-in handshake from a reply
Confirms a pending double opt-in handshake from the recipient’s relayed reply text. Only an affirmative keyword (YES / START / SUBSCRIBE and multilingual variants — the exact set the carrier inbound path recognises) against a PENDING prompt records consent: it writes the same opted_in consent row the inbound YES handler writes and marks the pending row confirmed. An affirmative reply for an already-confirmed pair is an idempotent success; an affirmative reply with no pending prompt returns 409; a non-affirmative reply leaves consent state untouched (STOP fan-out is owned by the inbound webhook). Records state only — it sends nothing and originates no outbound message on its own.
