feat(kiosk): language selection as first setup step + screensaver step

- SetupActivity: new Step 0 — language picker (IT/EN/DE) with large buttons,
  hardcoded trilingual title so it's always readable; saves 'kiosk_language' pref,
  calls recreate() via onSaveInstanceState to reload the Activity in chosen locale
- SetupActivity: new Step 5 — screensaver toggle (before Done), saves 'screensaver_enabled'
- All existing steps shifted: Welcome→1, Permissions→2, Server→3, Scale→4, Done→6
- Progress dots updated to 5 dots (steps 1-5)
- attachBaseContext override in SetupActivity, KioskActivity, SettingsActivity to
  apply the saved locale to all Activities via SetupActivity.applyLocale()
- buildSummary now shows language, screensaver setting, and scale status
- New string resources: setup_screensaver_*, summary_lang, summary_scale_skip,
  summary_screensaver_on/off in IT, EN, DE
