feat(demarche): sign up when prefilling a dossier (#8247)
* store prefill params in session

Instead of using query params on /dossier/new, we assume the user comes
from /commencer/:path, which is the new prefill link.

There, we store the prefill params in session, and use them to prefill
the dossier when creating it, in /dossiers/new.

* spec: cover the case

* review: serialize with json instead of yaml

* review: rename method

* review: store only query params

* review: comment why we dont override already stored params
