feat(bot): Коммит — навигация по дереву репозитория загрузок

- UploadsRepo: локальный клон, fetch не чаще fetch_interval, ls-tree -z (пробелы/кириллица),
  cat-file, последний коммит по пути; git без shell, ssh с -F /dev/null (без конфига хоста)
- «📝 Коммит»: папки/файлы с размерами, ⬆️ Вверх, страницы по 20, карточка файла
  с последним коммитом, «👁 Показать» (<pre> или документом); в кнопках только индексы
- ключ для контейнера: GIT_SSH_KEY_B64 → временный файл 0600 (смонтированный файл хоста
  контейнерному uid не прочитать); volume /data для клона
- тесты на настоящем bare-репозитории во временной папке
