ELI: New Order Notifications

Every order has people who need to know, and they are rarely the same people. Order Notifications uses recipient rules: each rule decides who gets notified, which orders trigger it, and how much they can see. Start from a role preset, filter by vendor, product, total or country, and deliver by Slack or webhook. Privacy-first: only read_orders access, each recipient sees only the fields you allow, and duplicate events never send twice.
