fix: actions (créer/éditer/supprimer/expand) sur dossiers/fichiers niveau 2+

Refactor complet de renderChildren:
- window._wsData exposé dans init() (au lieu de document.querySelector)
- data-ws-action + data-ws-id + data-ws-name sur les boutons d'action
- Event delegation: handleTreeAction() sur le <ul> via @click Alpine
- Suppression de event.stopPropagation() qui bloquait la délégation
- Chevron: onclick utilise window._wsData, data-ws-id ajouté
- Drag & drop + hover: utilisent window._wsData

Toutes les actions fonctionnent maintenant à n'importe quel niveau de profondeur.
