Операции, прерванные перезапуском панели, закрываются при старте; снимки: исправления по ревью

- core.interrupt_orphaned_operations() при запуске панели, active_operations_for() по всем задачам
- снимки: имена с пробелами, снимки вне панели без кнопок, --force только на «revert requires force»,
  память на паузе учитывается, защита от двойного нажатия, надпись «Создаём снимок…»
