feat(webhook): v2 webhooks foundation — DB schema + JPA entities
Phase 1 v2 фичи Webhooks: HTTP callback delivery параллельно с Kafka
publishing для consumer'ов которые не могут Kafka subscribe (геопортал
PHP, legacy admin-ui'и, BI-системы).
Migrations:
- 0013-webhook-subscriptions: таблица + check constraints (URL scheme,
scope enum) + partial index по active=true для hot poller path
- 0014-webhook-deliveries: tracking каждой попытки доставки (один
subscription × event = uniq), partial index due (status IN pending,
retrying), DLQ index, FK на outbox_events с CASCADE delete
JPA entities:
- WebhookSubscription: TEXT[] filters (scope, dictionary, event_type),
HMAC-SHA256 hex secret, active flag, audit fields
- WebhookDelivery: lifecycle pending → retrying → delivered/dlq,
exponential backoff schedule (1m → 5m → 15m → 1h → 6h → 24h capped),
MAX_ATTEMPTS=1000 (consistent с outbox), markDelivered/markFailed/
resetDlq business methods
Repositories:
- WebhookSubscriptionRepository: findActive() через partial index
- WebhookDeliveryRepository: findDue() для poller, INSERT ON CONFLICT
DO NOTHING для idempotency, DLQ counts для метрик
Ещё впереди: WebhookDispatcher service (HTTP POST + HMAC + SSRF guard),
REST API CRUD (admin-only RBAC), admin-ui /webhooks page, тесты.
