doc: add note about tt integrity check

+"``integrity-check-period`` работает только в связке ``tt`` + Tarantool, где ``tt`` периодически проверяет целостность запущенного экземпляра. "
+"В TCM параметр не используется, так как компонент лишь загружает и проверяет подписи конфигураций, не взаимодействуя напрямую с базой данных. "
