Action Network + Stay AI Integration

Keep Action Network and Stay AI aligned: when marketing events happen in one, update the other automatically.

Example: when Stay AI's "Watch Orders" fires, WEXTL can "Create Attendance" in Action Network. Action Network has 25 actions (including Create Attendance, Create Event, and Create Outreach); Stay AI has 25 actions (including Add Subscription Discount, Add Subscription Metadata, and Add Subscription Order Lines).
