fix: kiosk settings button position + opened-item expiry badge consistency

- kiosk: add gear button (⚙) to the left overlay (between ✕ and ↻)
  so settings are reachable from within kiosk mode without a native
  Android button. The web button calls showPage('settings').
- kiosk: permanently hide the native Android settings button via
  setNativeSettingsVisible(false) after overlay injection. Removes the
  touch bleed-through that caused the camera button tap to open kiosk
  settings instead of the scan page.
- kiosk: closeModal() no longer restores native settings visibility
  (native button is replaced, must stay hidden)
- dashboard opened-items panel: items expired by opened shelf-life but
  classified as safe by getExpiredSafety (level='ok', e.g. jam,
  condiments) now show a gentler amber 'Check soon' badge instead of
  the red ⛔ 'Scaduto!' that was misleading users. Red ⛔ is now
  reserved for warning/danger safety levels only, consistent with the
  top banner which already filtered out safe-level expired items.
- header: version label corrected to v1.7.13
- translations: added expiry.badge_check_soon (it/en/de)
