New Profile Backup restore: No Back Button on wrong entered Passphrase-Words

[TimoGoetze]

On Grapheneos, current version

When you add a new User or do the first time initialisation of grapheneos, you are asked if you want to restore an existing backup. Choose to restore, plug in USB storage and you are asked for the 12 passphrase words. If you make a typo somewhere, simply no backups are found. There is only a red warning that it might be that the passphrase was wrong.

There is no Back Button, which is the bug. You cannot check, re enter or correct your passphrase and try again. If you fail here, you have no chance to restore any backup. even not via systen/backup menu because of force to generate new passphrase.

Only chance is to factory reset the whole phone or delete and create a new additional user profile.

The words should have a checksum, warning you about impossible combinations and unknown words. But yeah, we should allow retries in setup wizard.
