Add newsletter poll responses to central results sheet

Newsletter poll votes arrive as webhooks and go uncollected, leaving campaign managers without a reliable response log. Capture responses into a shared sheet for same-day segmentation and reporting.

Overview

Newsletter poll responses often arrive as raw webhook payloads and never reach a single source of truth; this flow captures every vote and writes it to a shared results sheet. That delivers segmentation-ready data to campaign managers and marketing ops the same day for prompt follow-up.
