fix: Исправлены синтаксические ошибки и добавлены миграции

Исправлено:
- channels.py: удалены осиротевшие строки после рефакторинга
- api/v1/notifications/urls.py: исправлен file для реэкспорта
- notifications/urls.py: создан для обратной совместимости

Миграции:
- 0010_userchannelpreferences_and_more.py: переход на v2 модели
  * Notification с GenericForeignKey (actor/action_object/target)
  * UserChannelPreferences вместо UserNotificationSettings
  * Удалены старые модели (NotificationCategory, NotificationType и тд.)
  * Переименована таблица в notifications_notification_v2
