users.json — saved Security Center credentials
================================================

Both APIBridge.Metro (GUI) and WINKSCData (console) can read a users.json
file at startup so you don't have to retype host / username / password
every time.

Search order (first hit wins):
  1. users.json in the same folder as the .exe   (portable mode)
  2. %APPDATA%\WINKStreaming\users.json          (per-user, written by Save)

Schema:
  {
    "host": "10.18.183.20",
    "username": "YOUR_SDK_USER",
    "password": "YOUR_PASSWORD",
    "useDemoCertificate": false
  }

GUI: open the "Connect to Security Center" tab, fill the fields, click
"Save Credentials". Writes to %APPDATA%\WINKStreaming\users.json.

Console: command-line args (-h / -u / -p) always win. users.json fills
in only the fields you did NOT pass on the command line. This lets
scripted/CI runs override what's saved.

SECURITY NOTE: users.json stores credentials in PLAIN TEXT. It is
written readable only to the current user (NTFS inherits the parent
%APPDATA% ACL). If you need stronger protection, do not save credentials
and instead pass them on the command line or via environment variables.
