Smart lists and a system event catalog
Audience lists that filter on email activity and membership, plus a centralized catalog of system events.
Added
4- AudienceSmart lists resolve their members from filters rather than a fixed set - filter on email activity (opened, clicked, campaign, template, delivery status), list membership, or any native audience field, combined with AND.
- AudienceA preview endpoint, so you can see who a smart list matches before saving it, and edit the filters on an existing list afterwards.
- NotificationsSystem events for audience, email, push and forms, with the event enums centralized in one place.
- SecurityProduction startup now refuses to boot without JWT and OAuth2 secrets set, rather than falling back to defaults.
