Asynchronous Export Progress Updates. (openemr#6977)
* Asynchronous Export Progress Updates. This change adds progress indicators to the export process. It will loop through each batch individually and process the batch while reporting progress in 5 second intervals on the currently processed batch. If a batch fails it can be retried. Added a new column to the task to hold the current result progress. Changed up the index page to function as both the main index and an ajax controller. Probably could break this apart but for expediency did it this way. * Fix escaping, deprecation notices. Had an escaping issue on the twig file. There were a number of dynamic properties created in php 8.2. Thanks to @stephen.waite for pointing them out.
