Rework the account creation screen

The loading bar (no name) appearing at the beginning is confusing. We should have something like

- Icon with a button to change it -> no name displayed, no address
- Field to enter a name for the account

Next page
- recovery phrase
- recovery confirmation

Next page
- password
- password confirmation

Done

-> the address will be shown in the account overview
-> no need to show a confirmation screen

We should have a "back" button next to the "next"

The arrow at the top left should go back to the account overview with a modal saying "You are about to leave the account creation process - confirm - cancel"
