Backend: - Translate all recognition prompts (receipt, products, dish) from Russian to English - Add lang parameter to Recognizer interface and pass locale.FromContext in handlers - DishResult type uses candidates array for multi-candidate responses Client: - Add meal tracking: diary provider, date selector, meal type model - DishResult parser: backward-compatible with legacy flat format and new candidates format - DishResultScreen: sticky bottom button, full-width portion/meal-type inputs, КБЖУ disclaimer moved under nutrition card, add date field to diary POST body - Recognition prompts now return dish/product names in user's preferred language - Onboarding, profile, home screen visual updates Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
