- Introduced a new customers/purchasing_summary webhook for detailed purchase data.
- Replaced tags, email_marketing_consent, and sms_marketing_consent fields with dedicated webhook topics (customer.tags_added/removed, customers/email_marketing_consent_update, customers/marketing_consent_update).
- Removed last_order_id, last_order_name (deprecated), total_spent, and orders_count from existing customer payloads; these are now provided via the new purchasing_summary webhook.
