fix: corriger position fixed du HelpButton et cache IndexedDB

- PageTransition: supprimer transform apres animation pour que
  position:fixed fonctionne correctement (le transform CSS cree
  un nouveau containing block qui casse le positionnement fixed)
- LoadingStatusBadge: tooltip adaptatif (meme largeur que le badge)
- main.tsx: exclure energy-providers/offers de la persistence IndexedDB
