SystemInfo.DeviceModel is not captured in event logs

[TTalpey]

The SystemInfo.DeviceModel property is captured by the Aptabase MAUI client at startup and is sent with TrackEvent(), but it does not appear in events exported later in the web UI. This value is highly useful in correlating issues to types of devices, for example I've found that OnePlus devices behave quite differently from other Androids, and XBoxen are similarly different from Windows desktops.

Please consider adding this to the export. If it's considered somehow to be PII, then perhaps it should be removed from the JSON content transmitted by the client.

We're planning on exposing it in the UI as well
