Refactor the configuration of enabled archives to be known to the GetArchive REST API handler so it can allow only formats that have been enabled by the administrator. Use the order listed in download.archive to configure the web interface, with no formats enabled if the list is empty. Default to all archive formats enabled, matching the schemes.
