fix(Test-WeakADPasswords): prevent report column truncation

$testResults | Out-String used the default formatter width, which
truncates long columns at the console/default width. The report text
is re-parsed line-by-line to attach "UPN:" annotations, taking the
first whitespace token as SamAccountName - a truncated account name
would silently fail to match $dictionarySamToUpn and drop the
annotation with no error. Pass -Width 4096 to avoid truncation.
