Add new daily log dashboard and macro summary

Introduces a new route and template for an enhanced daily log dashboard with macro nutrient summary. Refactors FoodItem model to add type annotations and a macros() method, and updates form handling to default missing values to zero. Also adds a navigation link to the new dashboard in the base template.
