Items : layout exactement identique à la fiche Anomalie

- Classes .anomaly-body/.anomaly-section/.anomaly-section-title/.anomaly-editor-wrap
  promues au niveau partagé (.fvtt-celestopol.item)
- Templates equipment/weapon/armure/aspect utilisent ces classes exactes
- Suppression des anciens mixins item-body-mixin etc.
