 * Processes a polled webhook event directly, bypassing the HTTP trigger route.
 * Used by polling services (Gmail, Outlook, IMAP, RSS) to avoid the self-POST
 * anti-pattern where they would otherwise POST back to /api/webhooks/trigger/{path}.

 * Performs only the steps actually needed for polling providers:
 * admission control, preprocessing, block existence check, and queue execution.
