feat: preloader smooth fade ticker; fix asiago shelf life; kiosk 5-lang wizard (ES/FR + Gemini/Bring steps)

Preloader:
- Replace 3D wheel with smooth fade-in ticker queue
- Bigger text (clamp 1.1–1.35rem), green/amber/red per check state
- Previous items fade upward at decreasing opacity
- Wider container (min(96vw,860px)) — no more awkward line-wrapping
- JS already used ticker-item/state-ok/warn/error classes (CSS was missing)

Shelf life — Asiago sottovuoto fix:
- estimateSealedExpiryDaysPHP() and estimateExpiryDays() JS:
  asiago/fontina/emmental/gruyere/scamorza now grouped with hard cheeses (60d base)
  vacuum sealed: 60 × 2.5 = 150 days — correct for fridge + sottovuoto
- Cleared stale opened_shelf_cache entry for 'Formaggio Asiago fresco'

Kiosk wizard:
- 5 languages: values-es/ and values-fr/ created (97 strings each)
- values/, values-it/, values-de/: complete rewrite with new keys
  (ble_connecting, ble_connecting_to, summary_scale_ok/warn, Gemini/Bring step strings)
  stepDone hardcoded Italian → @string refs; screensaver nav → @string/setup_step_back/next
- SetupActivity.kt: steps 0-8 fully implemented; ES/FR language selection;
  auto-skip Gemini/Bring if already configured; buildSummary() localised;
  finishSetup() sends gemini_api_key + bring_email/password; BLE connecting
  strings localised; scale summary lines use R.string
