Communication service
Transactional email for OTP, welcome, bill invites, and bulk sends. Tracks delivery logs and provider quota, accepts provider webhooks, and consumes the auth welcome-email stream. An older note described this module as a library only; the runnable service on port 8087 is the current delivery plane.

Responsibilities
- Own its schema and Flyway migrations. Other services call HTTP or consume events. They do not join this schema.
- Expose public routes only through Kong. Internal routes use the internal API key.
- Publish integration facts through the transactional outbox when this service produces events. The outbox relay is the publisher.
Kong prefixes
/api/v1/communication/email/preview/api/v1/communication/delivery-logs/api/v1/communication/email/usage- Provider webhooks: resend, brevo, mailjet, mailtrap, sendpulse
Public clients use http://localhost:8080/api in dev and https://api.splick.app/api in production. Kong strips the /api prefix before the upstream.
