debug: console.log dans onContextMenu + revert au fichier stable

- Ajouté console.log('onContextMenu fired') pour diagnostiquer si le handler
  Alpine est bien appelé au clic droit
- Fichier local_workspace.html restauré depuis b32b94e (sans le handler
  natif cassé qui causait des erreurs Alpine)
- Vérifier la console navigateur: si 'onContextMenu fired' apparaît au
  clic droit, le problème est post-handler. Sinon, c'est Alpine/l'événement
