Jules Neny	1033099663	fix(v13-p0): iframe AEP skeleton timeout fallback (resolves loading stuck) Le @load event ne fire pas (ou tardivement) sur l'iframe AEP enfermee dans un wrapper avec transform scale(0.42) + viewport simulee 1440px. Resultat : skeleton 'Chargement de la carte AEP...' reste affiche indefiniment, masquant l'iframe meme si elle se charge. Fix : - setTimeout 2.5s dans onMounted qui force revealIframe() inconditionnellement - onIframeLoad clear le timer si l'event fire dans les temps (cas nominal) - retrait du z-10 sur le skeleton (defense en profondeur : si bug residuel, l'iframe sera quand meme visible derriere) - factorisation revealIframe() partagee entre @load et fallback - cleanup du timer dans onUnmounted Build SSR : 5 pages, 0 warning, ~4s.
