cli: improve passphrase input experience — heartwood

When an incorrect passphrase is entered, the characters are not removed. Unfortunately, this is due to the upstream library we are using[0].

To improve the experience, however, the with_display_toggle_enabled can be used to reveal the user’s input using the Ctrl+R hotkey. They can then reveal the password, if able to, and fix the problematic input.

Once the feature request in the upstream library is made, that can be used instead.
