- * Главная страница приложения для управления бюджетом.
- * 
- * Этот виджет является основным экраном приложения и содержит:
- * - AppBar с заголовком и кнопкой настроек
- * - Основной контент с приветственным сообщением
- * 
- * Особенности реализации:
- * 1. Наследуется от StatelessWidget, так как не содержит собственного состояния
- * 2. Использует Material Design через Scaffold
- * 3. Управление темой вынесено в SettingsService
