Calculate checksum word on import

[kayth21]

Like with Coldcard or Bitbox02, Passport should calculate and display all possible checksum words on import and let the user pick one, if only 11 or 23 words were entered. This allows seed creation by drawing seed words out of a “hat” which removes the need to trust the random number generator from Passport.

Thanks for the suggestion @kayth1, we actually have a task in our backlog that we hope will satisfy your suggestion.

Once we've completed and released the feature I'll notify you here before closing the issue.
