fix: comprehensive shopping name audit + README update

Shopping name system hardening (api/index.php):
- phraseMap: added sugar subtypes (zucchero a velo), passato di verdure/patate
  → Verdure, aroma phrases → Ingredienti Spezie, farina 00 → Farina,
  explicit brodo subtypes; added ordering comment on 'farina integrale'
- keywordMap: added 'lievito' → Lievito, 'aroma' → Ingredienti Spezie
  single-token fallbacks

DB migration (sqlite3 direct):
- farina integrale / Farina integrale di grano tenero → Farina integrale (3 rows)
- Prodotto sconosciuto (Belbake, it:farina-integrale) → Farina integrale
- Zucchero di canna → Zucchero di canna
- Passato di patate e carote → Verdure (it's a blended veg purée)
- Aroma mandorla per dolci → Ingredienti Spezie (consistent with other aromas)
Total: 11 products re-classified

README.md:
- Shopping List: added generic shopping name feature + auto-add on depletion
- Cooking Mode: updated TTS description (browser / native Android / REST)
- Kiosk: added native TTS bridge bullet
- Roadmap: checked off 3 new completed items
