Update the Login Message String to show a custom message and not the name of the FileMaker File being signed into.

• Add the updated function call to the webdlanding.js file.

function setHeaderMessage() {
  let msg = document.getElementsByTagName('iframe')[0].contentDocument.getElementById('login_header_msg').innerHTML;
  
  if(msg) {
    // load message from AppModel defined below/later.
    msg.innerHTML = "Sign in to TEST system";
  } else {
    setTimeout(setHeaderMessage, 200);
  }
}

setTimeout(setHeaderMessage, 200);

• Also need to expose the message per AppModel by adding a new optional property.
