WMI Event Consumer created

// EVENT DEFINITION:

A WMI Event Consumer (`__EventConsumer`) was registered in the WMI repository for event-triggered execution.

// DETAILED TELEMETRY & CONTEXT:

Event ID 5861 (`Microsoft-Windows-WMI-Activity/Operational`) is the premier indicator for permanent WMI persistence (`__EventConsumer`, `__EventFilter`, and `__FilterToConsumerBinding`). When an adversary registers an `ActiveScriptEventConsumer` or `CommandLineEventConsumer`, event `5861` captures the full query, consumer name, and target command/script that will execute automatically upon system startup or specific triggers.
