Ability to revisit mnemonic phrase and return to main page

[IgorShadurin]

I would like to propose a user experience enhancement for consideration.

1 - I entered my login and password, then chose 'New Address'.
2 - After reading the mnemonic phrase, I accidentally clicked the 'OK' button.
3 - I found myself unable to return to the mnemonic phrase to double-check it.
4 - I also couldn't find a way to navigate back to the main page to create a new username/password combo.

For a smoother user experience, it would be great to implement these two features:

1 - Allow users to revisit the mnemonic phrase. We need to ensure users can confidently confirm they've noted their mnemonic correctly.
2 - Add a navigation option that lets users return to the main page. This would be useful for when users need to create a new username/password combo.
