fix: step_finalize — resolve ingredient names and prices in shopping list email

Preloads Ingredient names from the DB (ingredients JSONB has no name field),
deduplicates by ingredient name, looks up top-confidence IngredientGroceryMatch
per ingredient, and renders a rich 4-column HTML table (Ingredient | Qty | Unit |
At Lucky | Price) with an estimated total.
