fix: suppression boutons doublons Forge + delegation parent modal

- Retrait des 3 boutons (delete/cancel/save) de la barre Forge (doublons)
- Retrait des handlers JS associés dans editor-poc.html
- Le header parent ObsiGate reste visible quand Forge est ouvert
- Les boutons save/delete du parent délèguent à Forge via postMessage
- Forge écoute 'parent-save' et 'parent-delete' du parent
- state.editorVault/editorPath settés dans viewer.js pour le parent
