feat: добавлена система миграций БД и CI/CD пайплайны

- Создана система отслеживания миграций (MigrationRepository, таблица migrations)
- Добавлен скрипт apply_migrations.py для автоматического применения миграций
- Созданы CI/CD пайплайны (.github/workflows/ci.yml, deploy.yml)
- Обновлена документация по миграциям в database-patterns.md
- Миграции применяются автоматически при деплое в продакшн
