v3.14.2: the counter probe's verdict rule

The ladder only advances on cntr_low; any other verdict stops the search.
A stop on a non-por_ok verdict after at least one cntr_low keeps the value
anyway - the earlier rejection proves it is above the card's counter - but
the response reports success: false with counter_saved, the verdict and the
saved counter ("something is likely wrong with the security settings");
the PWA shows it amber.  Without a prior cntr_low nothing is saved, and a
missing PoR stays an error.  actual_response_sms_submit/ussd count as
accepted.
