Animations custom (video/GIF) + selection aleatoire

- Upload de GIF/MP4/WebM comme animations de compte a rebours
- Checkboxes pour activer/desactiver chaque animation (CSS + custom)
- Si plusieurs actives, tirage aleatoire a chaque photo
- Preview dans le backoffice avec tirage aleatoire
- Suppression des animations custom importees
- Les animations custom se jouent en plein ecran avant la capture
