test(e2e): helpers ne dépendent plus du signal __OBSIGATE_BOOTED retiré (bfe0c75)

bfe0c75 a retiré le splash et son signal de boot côté app sans adapter les
helpers des specs ; login() attendait window.__OBSIGATE_BOOTED → timeout
60 s × chaque test des 8 suites. Signal de rechange sans dépendance au
flag interne : document prêt ET premier .tree-item rendu (preuve que
l'init a lié données+handlers). Validé local : 14 passed sur les 3 suites
qui échouaient en CI (obsigate:ci v2.82.8, auth off, mêmes fixtures).
