Returns statistics for a specific mitigation device including Blocked Count, Not Blocked Count,
Total Count, and Score.

This endpoint works together with GET /v2/mitigation/devices to replace the deprecated
V1 endpoint. First retrieve the device list, then use this endpoint to get stats for
each device as needed.

Example workflow:**

1. Call GET /v2/mitigation/devices to get the list of devices

2. Call GET /v2/mitigation/devices/{DeviceId} to get stats for a specific device
