Implemented a new endpoint for restoring templates to their last applied state, allowing users to revert changes made since the last application. Updated the ScheduleTemplate class to include a snapshot of the last applied state, enabling rollback capabilities. Enhanced the frontend with a restore button in the ChannelDetail component, providing users with a confirmation prompt before executing the restore action. Localization updates were made to support new UI strings in both English and Russian, improving the overall user experience in template management.
