defined Meta ordering of the Item() model in apps.dashboard.models; Item() also now returns a __str__ result; in .forms, defined a specific use-case of is_valid() method; a pair of new UTs in .tests.test_models help confirm str representation and list order of items; .test_forms now ensures the .is-invalid bootstrap class is tested as a css class attr; migrations run; full UT & FT suite back to passing state (tho a refactor of flimsy form customizations is desperately needed)
