Returns a list of detected anomalies.
Anomalies can be sorted by startTime, severityLevel, or costOfAnomaly using sortBy and sortOrder. By default they are sorted by startTime in descending order (most recent first).
The sort order is total and reproducible: ties on the selected field are broken by startTime descending and then by anomaly id ascending, so the same result set always paginates in the same order.
The notifications array is always present on each anomaly item; it is empty unless includeNotifications=true is supplied.
Pagination stability: sortBy, sortOrder, filter, minCreationTime, and maxCreationTime must be held constant across a pagination sequence. A pageToken presented with any of them changed is rejected with 400.
