fix: jam/confiture opened shelf life in fridge 60→180 days

Both PHP and JS rules for opened confettura/marmellata in
section G (fridge condiments) were returning 60 days — too short.
An opened jar of jam lasts ~6 months in the fridge.

Also: update README roadmap with comprehensive, grouped view
matching the internal memory roadmap (high/medium/low/completed).

Fixes: database.php line ~412, app.js line ~1707

 ## 📋 Roadmap
 
-- [ ] User authentication / multi-user support
-- [ ] Offline mode with service worker
-- [ ] Export/import inventory data
-- [ ] Notification system (Telegram, email) for expiring products
+### High Priority
+- [ ] **Cooking mode — 3D wheel JS** — swipe navigation, gyroscope tilt, haptic feedback
+- [ ] **Cooking mode — step timers** — auto-detect "X minutes" in recipe steps, countdown + alert
+- [ ] **Push notifications** — daily expiry alerts via PWA Service Worker + VAPID
+- [ ] **Quick search / quick-add bar** — always-visible search above the nav, PWA shortcuts
+
+### Medium Priority
+- [ ] **Receipt OCR → bulk add** — photo of receipt → Gemini Vision → auto-fill inventory
+- [ ] **CSV/JSON export & import** — download/upload inventory from Settings
+- [ ] **Custom storage locations** — user-defined locations beyond Fridge/Freezer/Pantry
+- [ ] **Multi-user support** — PIN-based user distinction, action log with user label
+- [ ] **AI optimal purchase prediction** — suggest "buy X units of Y within Z days"
+- [ ] **Price history sparklines** — per-product price chart from the AI cache data
+
+### Low Priority / Nice to Have
+- [ ] **Dark mode** — CSS custom properties are already structured to support it
+- [ ] **Full offline mode** — Service Worker cache to show inventory read-only when server is down
+- [ ] **French & Spanish translations** (`fr.json`, `es.json`)
+- [ ] **Swipe actions on inventory rows** — swipe left to use/discard, right to edit
+- [ ] **PHP unit tests** — PHPUnit coverage for shelf-life, price calc, and key helpers
+
+### Completed ✅
+- ✅ AI price estimation in shopping list
+- ✅ Server heartbeat + offline banner
+- ✅ In-app bug reporter → automatic GitHub issue creation
+- ✅ Cooking mode (start, steps, 3D wheel CSS)
+- ✅ Kiosk ⚙️ Settings overlay button (replaces Android native button)
+- ✅ Adaptive consumption anomaly detection
+- ✅ CI/CD pipeline (PHP lint, JS lint, Docker build, Trivy security scan)
