fix: split Bimby/Cookeo appliances, add missing i18n keys, improve use_all dialog

- .env: split 'Bimby/Moulinex Cookeo' into 'Bimby' and 'Moulinex Cookeo'
- translations (it/en/de): add use_all_confirm_*, throw_all_confirm_*,
  confirm.cancel, confirm.proceed, location.dispensa/frigo/freezer
- app.js: when ANY opened package exists, always show disambiguation
  dialog ('solo questa confezione?' vs 'tutto?') instead of silently
  finishing one — was previously showing dialog only for 2+ opened packages
