feat(kiosk-wizard): step Features con screensaver, prezzi, piano pasti, zero-waste tips

Step 5 del wizard ora mostra 4 toggle (pre-compilati se già configurati):
  - Salvaschermo orologio (screensaver_enabled)
  - Prezzi lista spesa (price_enabled)
  - Piano pasti (meal_plan_enabled)
  - Suggerimenti zero-waste durante cottura (zerowaste_tips_enabled)

Solo i toggle NON ancora impostati in prefs partono da false (fresh install).
Tutti e 4 vengono salvati in SharedPreferences e inviati al server via
save_settings al completamento del wizard.

PHP/JS: zerowaste_tips_enabled aggiunto come impostazione server-side
(ZEROWASTE_TIPS_ENABLED in .env), sincronizzata nel WebView via
_applySyncedSettings() al caricamento.
