fix: ctxMenu réactivité Alpine — réassignation complète au lieu de propriétés

Alpine ne détecte pas les changements sur les propriétés imbriquées
d'un objet (ctxMenu.visible = true). Il faut réassigner l'objet entier:
this.ctxMenu = {visible:true, x:..., y:..., node:..., tags:...}

Impact: onContextMenu (show), ctxMenuOpenPage/OpenFolder/Rename/Duplicate/Delete (hide)
+ repositionnement dans nextTick
