fix(config): ложное предупреждение про AWG, сироты section_interface, дубль cron

- has_outbound_section: туннельные секции (awg/warp/vpn/openvpn/masque/
  anytls/snell/mieru/sudoku) теперь считаются исходящей конфигурацией -
  одинокая AWG-секция больше не получает вводящее в заблуждение
  «No proxy outbound sections found» (жалобы пользователей #39/#42)
- новая миграция orphan_section_interface_cleanup: удаление секции
  маршрутизации раньше оставляло после себя дочерние section_interface,
  ссылающиеся на несуществующего родителя (у пользователя - запись на
  секцию '2' при живой только '1'); сироты удаляются через новую операцию
  delete_section; функция объявлена до массива MIGRATIONS - ucode не
  поднимает объявления
- strip_unmarked_tachyon_cron_lines: старые версии писали cron-строки без
  маркер-комментария, они переживали фильтрацию по маркерам, копились при
  обновлениях и crond запускал component_updates_if_due дважды за тик;
  немаркированные строки с нашими командами теперь вычищаются при каждом
  refresh и remove
