refactor(db): консолидация миграций и рефакторинг кода

Объединены изменения из промежуточных миграций в начальные миграции для упрощения истории базы данных.
Удалены миграции: accounts/0002, discounts/0002, orders/0003-0004, products/0002-0005, user_roles/0002, system_settings/0001-0002, integrations/0001-0002.
Добавлена автоматическая creation пользователя при установке пароля.
Обновлен UI страницы установки пароля с кастомным стилем.
Добавлен conditional rendering для кнопки синхронизации Recommerce.
Исправлены редиректы с 'index' на '/' в accounts views.
Добавлена проверка request.tenant в navbar и authenticate метод в auth backend.
