GET /eventTypes

This is a read-only operation that queries and returns a list of audit event types. GET requests are idempotent and have no side effects. The tool does not create, modify, delete, or execute any actions—it only retrieves information about what event types exist in the audit system. This is consistent with Read category classification.
