Refactor how model visibility works in index actions: * Call `visible` in the controller instead of in model `search` methods. This decouples model visibility from model searching. * Explicitly pass CurrentUser when calling `visible`. This reduces hidden dependencies on the current user inside models. * Standardize on calling the method `visible`. In some places it was called `permitted` instead. * Add a `visible` base method to ApplicationModel.
