feat(api): profil machine éditable, sonde, et réglages globaux apt-cacher-ng

- machines : updateMachine (PATCH /machines/:id) + POST /machines/:id/probe
  (sonde synchrone → faits + proposition de correction) ; MachineView expose
  machineKind/virtualization ; CreateMachineInput accepte aptProxyMode persistent
- app_settings (clé/valeur, migration 0006) + service appSettings :
  défaut apt-cacher-ng (mode + url) ; applyProxyToAllMachines
- routes /settings : GET, PUT /apt-proxy, POST /apt-proxy/apply-all
