Bug Fixes

• Fixed device-mapper (LVM) device tagging in the diskv2 check to match Python psutil behavior. Previously, devices were reported as dm-X (e.g., device:dm-0) instead of their friendly /dev/mapper/* names (e.g., device:ocivolume-root). This ensures backward compatibility with the Python disk check and preserves existing dashboards and monitors.

• Fix an issue introduced in 7.73.0 that can cause the MSI to overwrite the site option in datadog.yaml with the default value of datadoghq.com.

  This issue impacts users who do not provide the SITE option to the MSI when upgrading AND who have an error in their datadog.yaml file that prevents the MSI from reading the existing site option (MSI log contains ReadConfig. User config could not be read).

  This issue also impacts users of datadog-installer.exe and Install-Datadog.ps1, introduced in 7.72.0, who do not provide the DD_SITE environment variable when upgrading.
