feat: ajout de serveurs depuis l'app + charte flamme sombre

- backend: GET /api/containers (liste lisible), POST/DELETE /api/servers
  (serveurs custom persistés en /data/servers.json, mergés aux intégrés),
  champ custom dans le statut.
- app: écran AddServer (form + sélecteur multi-conteneurs filtrable), FAB
  Ajouter, suppression depuis le détail (serveurs custom only).
- thème: palette flamme/chaud sombre (anthracite + orange→rouge), remplace le
  Material violet/teal par défaut (scaffold, appbar, tabs, boutons, FAB, champs).
