Разделы, фильтры и просмотр текстов в UI; опция «не хранить видео»

- таблица sections (дерево через parent_id), у видео section_id
- API: CRUD /sections, фильтры /videos (поиск, раздел с потомками, метод),
  GET /videos/{id}/text, PATCH раздела, DELETE вместе с файлами
- pipeline: keep_video=false удаляет mp4 после расшифровки, section_id
- UI: панель разделов с вложенностью и счётчиками, поиск, фильтр по методу,
  диалоги полного текста/выжимки, привязка к разделу, удаление,
  переключатель «Сохранять видео на диске»
- compose: bind-mount ./web для правок без пересборки
