Améliore l'affichage de plusieurs petits formulaires résiduels

[colinux]

Plusieurs forms à l'ancien design ont été plus ou moins visuellement cassés suite à l'intégration des erreurs au DSFR (cf #9004)

Cette PR transforme rapidement ces forms au DSFR, ou rajoute le margin manquant suivant les cas.
Il resterait idéalement à adapter l'éditeur des champs, mais c'est plus touchy vu son importance (plus de bordure sur le champ description)

Sur le form des services j'en ai profité pour remplacer les placeholders par les hints avec exemples.

Question bonus: l'InputComponent n'affiche pas (plus?) l'astérisque à côté du label quand il est required. Est-ce qu'on a un consensus (qui m'aurait échappé) pour l'enlever sur l'ensemble des formulaires ?
