[MVC] Полная миграция на MVC архитектуру

- Создано ядро MVC: App, Router, Controller, Model, View, Database
- Созданы модели: User, Product, Category, Cart, Order
- Созданы контроллеры: Home, Auth, Product, Cart, Order, Page, Admin
- Созданы layouts и partials для представлений
- Добавлены все views для страниц
- Настроена маршрутизация с чистыми URL
- Обновлена конфигурация Docker и Apache для mod_rewrite
- Добавлена единая точка входа public/index.php
