Affichage de la version dans la page Paramètres du site

Ajoute une section "Version du logiciel" dans admin/parametres avec :
- version installée + date d'installation
- bandeau de mise à jour disponible si nouvelle version détectée
- badge "À jour" si à jour (même logique que le tableau de bord admin)
