[CAM-13938] Refactor Webapps to use central utility function to do $scope.$apply()

The following pattern is used at many places in the Webapps:

const phase = $scope.$root.$$phase;
if (phase !== '$apply' && phase !== '$digest') {
  $scope.$apply();
}

Let's create a central utility function for it and refactor the codebase.
