Let the user resume a schema at the last page they where at

### Description

In v3, the frontend was able to remember the last page that a user was on and send them there directly when resuming (when using the same browser). We would like this functionality in v4 as well since our surveys consist of many pages, and having to navigate, say 12 pages, already filled out is cumbersome.

I believe this worked for both our statefull and stateless apps.

I.e the user navigates to page 3, closes the browser, then later in the day resumes the schema in the same browser, the user would be sent directly to page 3.

### Additional Information

_No response_

No files or tests are named. Start by tracing the v4 resume flow and comparing it with the v3 frontend behavior; verify how the current frontend handles resuming in both stateful and stateless apps. Done means a user returning in the same browser is sent to the last page they visited.
