Enrichit les declencheurs/actions de scene (clic/survol/affichage, surbrillance/video/son/visibilite/indication/attendre) et fiabilise la pose d'un fond/decor importe

- Ajoute clic/survol/affichage-ecran comme declencheurs, et surbrillance,
  video, son, visibilite, indication, attendre comme actions, utilisables
  aussi bien par l'editeur manuel (menu lateral Objets/Ecran) que par
  Ruby (IA), avec blocs deplacables/supprimables dans une chaine.
- Corrige plusieurs variantes du bug "impossible de poser un objet hors
  du champ de la camera" (troncature du chainage d'actions a 4 maillons,
  fond importe pose a 128x128 au lieu de sa taille reelle, decalage du
  fond au vrai glisser-depose, redimensionnement manuel jamais propage
  au monde).
- Ajoute un vrai glisser-depose depuis la galerie vers la scene, la
  gestion complete de "Mes assets" (sous-sections Fonds/Decors/Sons/
  Videos, suppression, reclassement fond<->decor sans re-upload).
- Ajoute l'upload de son (limite 3 min) et de video (MP4 uniquement,
  limite 5 min), avec validation de la duree reelle du fichier, et une
  replique audio optionnelle dans une bulle de dialogue.
- Fixe la taille de pose d'un objet/decor importe a 200x200 avec une
  boite de collision de 150x150.
- Filtre le selecteur de fichier des actions son/video par type reel.
