Notification supervisor for reckon-db

Manages notification-related components using rest_for_one strategy: - LeaderSystem (leader responsibilities, tracking) - EmitterSystem (event distribution workers) - SubscriptionHealthMonitor (periodic health checks)

rest_for_one ensures that if LeaderSystem crashes, EmitterSystem and HealthMonitor are also restarted, preventing stale emitter pools from outliving their leader tracking infrastructure.
