Add admin user details and logging in PrivacyModel

Introduced a new `adminUserName` variable and a constant `DEFAULT_PASSWORD` in `Privacy.cshtml.cs`. Updated the `OnGet` method to handle a "drive" query parameter, construct a disk space command, and log the command string along with the admin username.
