  Vivo IMEI activation: stop spending captchas on line items with no IMEI
  
  76% of production captcha rejections were line items whose serial number is
  null. Vivo answers those with {"msg":"参数为空"} -- "parameter is empty" --
  and status 0, which this code recorded as a captcha failure. So a correctly
  solved captcha looked wrong, no activated_imei row was written, the line item
  stayed pending, and it came back every 5 minutes indefinitely. Those rows were
  permanently consuming roughly 43% of the run quota, which is why every tick ran
  full at 20/20 and the backlog never drained.
  
  It also made the model look far worse than it is: measured accept rate 44%,
  while the same solver scores 85-93% when the IMEI is present. True captcha
  accuracy is around 77%.
  
  Fixed at source: both named queries now exclude null and blank serial numbers,
  so such line items never enter the pool (this also covers the Realme caller).
  The loop additionally skips them before fetching a captcha, so no captcha,
  solver call or Vivo request is spent discovering it.
  
  Found via the diagnostics added in r37407 -- the previous log line recorded
  five words and discarded the response that named the cause.
