Azure Service Bus

The app supports Azure Service Bus for audit event processing as an alternative to the default in-memory queue.

• Configure the connection string in appsettings.json under ServiceBus:ConnectionString
• Queue name: audit-events
• The Azure subscription is active until 23 March 2026 — after that date the Service Bus resource will be unavailable and the app will fall back to the in-memory queue
