L'historique des scans ne se mettait pas à jour après un POST sur
/api/discovery : le Server Component restait servi depuis le cache
route de Next.

- discovery-launcher : appelle router.refresh() après un scan
  réussi pour invalider le cache et re-rendre la page parent.
- scans/page.tsx + hosts/page.tsx : déclare `dynamic = 'force-dynamic'`
  et `revalidate = 0`. Sans ça, Next pouvait statifier ces routes au
  build (mode standalone) puisque la fonction getX() ne fait pas
  appel à un signal dynamique.
