Created set password storybook

Closes #179 (closed)

This implements the set password phase during reset password.

• Implements state and a guard to prevent the user from going to other parts of passit while "logged in" with the email and backup code
• Reuses the current backup code for the new private key. In the future we may want to offer a option to immediately download a new one. My thinking here is that password recovery is more likely to be the user forgot the password than for an attacker to potentially have the back up code. It's unlike change password where a leak scenario is more possible.
