Introduces caching for ingredients in IngredientService and AddRecipeViewModel to reduce database calls and improve performance. Adds cache invalidation after ingredient modifications and debounced nutritional value calculations to prevent redundant computations during rapid changes. Updates AddRecipePage to use debounced async recalculation, and refactors related methods to leverage the new caching and debouncing mechanisms.
Introduces async database migration and reset logic in MauiProgram and exposes them via new commands in SettingsViewModel. Updates SettingsPage UI to provide migration and reset controls with status feedback, adds related styles, and integrates new converters. Also improves AddRecipeViewModel validation and logging, and minor style/color resource updates.
Updated BoolToColorConverter to provide theme-aware colors for text, borders, and backgrounds, supporting both light and dark modes. Refactored AddRecipePage.xaml and IngredientFormPage.xaml to use a modern tab bar style with underline indicators, improved color handling, and increased tab button font size for better usability and visual consistency.
Replaced the default SearchBar on IngredientsPage and RecipesPage with a custom modern search bar using Frame, Entry, and a clear button. Added new styles for the modern search bar components in Styles.xaml. Introduced ClearSearchCommand in both IngredientsViewModel and RecipeViewModel to support clearing the search text.
Introduced a reusable FloatingActionButton style in Styles.xaml and replaced the top action buttons on IngredientsPage and RecipesPage with floating action buttons. Updated the RecipesPage code-behind to remove the now-unnecessary OnAddRecipeClicked handler, switching to command-based navigation for consistency.
Introduced reusable styles for list items, nutrition info, and delete buttons in Styles.xaml. Refactored IngredientsPage.xaml and RecipesPage.xaml to use these styles, improving visual consistency and maintainability across the app.

Database Migration, Validation, and Seeding Improvements
