Mini menu client + luminosite impression + endpoints systeme

- Menu client coin haut-gauche : WiFi, luminosite, relancer, redemarrer, eteindre
- Popup WiFi : scan, statut, connexion (reutilise les endpoints existants)
- Popup luminosite : slider -50% a +50%, ajuste la luminosite avant impression
  (ImageEnhance.Brightness dans _preparer_image)
- Endpoints systeme : /api/systeme/eteindre, redemarrer, redemarrer-app
- Endpoint exposition Canon : /api/camera/exposition (GET choix + POST valeur)
