Extract snackbar notifications to UISnackbars utility

Centralises all SnackBar calls behind UISnackbars.showError/showSuccess/
showWarning/showInfo, each themed via AppColorExtension. New warning and
info colour tokens added to both themes. Calling any method clears any
visible snackbar before showing the new one.
