Feature: Improve wallet seed phrase entry

[TurboAI]

Is your feature request related to a problem? Please describe.
For recovering the wallet from a seed phrase you have to copy and paste/type in individual words, and they have to be tab-separated.

Describe the solution you'd like
I would like for the words to be able to be space-separated (so pressing space after manually typing each word takes you to the next text box), and allow copy and pasting of the whole seed phrase (space-separated) in the first box to fill all the boxes.

Describe alternatives you've considered
N/A, please comment any suggestions. I understand this may not have been a priority to encourage paper storage of seed phrases, and not digital storage on a hot machine, but I think a lot of users would appreciate this feature nonetheless.
