[Enhancement] allow re-type seed words if checksum not valid

[htprww]

Describe the new feature or enhancement

I got into this issue that when I restore the wallet using seed words, I have a typo in one of the words, and did not pass the final checksum. Then the krux gets back to the Restore wallet main menu, so I have to re-type all.

I would like to stay in the seed words typing page, and allow the users to navigate back the word list, so I can just fix the typo for the single word.
