* fix: "remove" a champ to prefill
Removing a champ to prefill on /preremplir used to fail, because of a
collusion (having the same form multiple times on un page looks like a
bad idea, when it comes to multiple input fields).
* fix specs
* feat(dossier): prefill drop down list champ
* decorate the types de champ to avoid if / else
In order to avoid doing if this a drop down ? / else at several places,
we decorate the types de champ and let the decorator give the possible
and example values.
* show all possible values when there are too many
* allow to prefill 'other' option
* review: remove duplicate
* review: refactor for readability
* validate that value is in options
* review: exclude disabled options
* feat(demarche): description
Show the description of an opendata procedure (published or draft),
with help about how to prefill a dossier for this procedure.
