v1.7.8: Trasferisci a Ricette dalla chat (refactor)

- Sostituisce 'Usa ingredienti' inline con 'Trasferisci a Ricette'
- Nuovo endpoint chat_to_recipe: Gemini restituisce JSON completo
  (title, meal, servings, ingredients, steps, nutrition_note),
  PHP arricchisce tutti gli ingredienti con product_id/location
  via fuzzy-match identico a generateRecipe
- La ricetta viene salvata in archivio e si apre nell'overlay Ricette
  con tutti i pulsanti Usa, modalità cottura, salvataggio intatto
- Rimossi: chatExtractIngredients, _buildChatIngredientPanelHTML,
  _chatRecipeTitle, chat_extract_recipe, chat-recipe-panel CSS
