Feature request: Allow users to insert seed / passphrases / master hd key

Hello

I miss the ability to insert my own passphrase while creating a new wallet.
I am currently using a blank wallet with a single private key that is imported with the console which has no hdseed.

This is an example of how Raven Core solved it with the extended seed words.

Thank you very much


Start by reviewing the wallet-creation flow and the console path used to import a private key, then compare how Raven Core handles extended seed words. Done means users can provide a passphrase, seed, or master HD key when creating a wallet, including the blank-wallet case described here.
