Change JavaScript Alert Text and Buttons

[Adam3371]

Why

In the signup process when navigating back, we show the user a JavaScript dialog in the browser that asks the user if he wants to continue the signup. Here the CTA ("OK"-button) should lead to a signup abort and the cancel should return to the signup process. (At this time it's the other way around)

TODOS

• If a signup is aborted by the user's back navigation, show following text and if possible, also display it in 2 lines.
  Are you sure you want to abort the signup process?

  Any information you’ve entered will be lost.
• Swap the actions of the buttons: "Ok" should abort the signup process and "Cancel" should return to the signup flow.
• If possible, change the text of the "Ok" button to "Abort".

Acceptance criteria

• Continues to work on all devices.
