cnbugs f3cda67d9f Fix VPN verify: via-env→via-file, add pass_len debug logging ...

OpenVPN 2.7 Windows DCO passes username but NOT password as
environment variable with via-env mode. Switched to via-file:
  server.conf: auth-user-pass-verify script via-file
  verify.sh reads credentials from temp file ():
    line 1 = username, line 2 = password

Also added pass_len to debug log so we can immediately see
if the password was actually received by the script.
