Hide "template_key" in site settings configuration if not applicable

Hi @ scott_euser
I fixed this issue
Also, I changed the order for inputs. The 'loader_plugin' input is displayed first. It looks better if changing plugins in the select list

Thanks! Actually template_key is only relevant when auto-load is enabled, so I updated the code to just base it on that. Tricky part was getting the ajax and plugin check to control access working of course, glad you managed! Thanks!

I thought in the future you could create another plugin where template_key displaying and disable_auti_loading are hidden. But we can separate this logic if it needs in any moment
