clean up how we create toasts() [no longer try to reuse dom elements, just add new ones each time], support persistent notifications and close button or not [via separate booleans], created a clear message route and use that now in templates/base.html to clear FE messages. This will break for check dups as I am not setting persistence / close buttons correctly for those jobs, that is next. Converted move_files to new format
