fix: Storico nav icon, recipe title in transaction notes and log display

- index.html: replace broken byte with 📋 emoji in Storico nav button
- submitRecipeUse: pass 'Ricetta: <title>' as notes to inventory_use API
  so every ingredient use is linked to the recipe in the DB
- loadLog: render recipe note as small italic line 🍳 below log-detail row
- style.css: add .log-recipe-note style (0.75rem, muted, italic)
