test: expand test coverage across diary, product, savedrecipe, ingredient, menu, recognition
- Fix locale_test: add TestMain to pre-populate Supported map so zh/es tests pass - Export pure functions for testability: ResolveWeekStart, MapCuisineSlug (menu + savedrecipe), MergeAndDeduplicate - Introduce repository interfaces (DiaryRepository, ProductRepository, SavedRecipeRepository, IngredientSearcher) in each handler; NewHandler now accepts interfaces — concrete *Repository still satisfies them - Add mock files: diary/mocks, product/mocks, savedrecipe/mocks - Add handler unit tests (no DB) for diary (8), product (8), savedrecipe (8), ingredient (5) - Add pure-function unit tests: menu/ResolveWeekStart (6), savedrecipe/MapCuisineSlug (5), recognition/MergeAndDeduplicate (6) - Add repository integration tests (//go:build integration): diary (4), product (6) - Extend recipe integration tests: GetByID_Found, GetByID_WithTranslation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
