Describe the bug

When exporting a collections report .csv, if the date range/file size is too large, the export will not contain all requested records. An incorrect/abbrieviated export does not contain malformed records, it just does not include all of them. An incorrect export does not have a constant size, but is always a fraction of the expected size. Perhaps a response chunking issue? The screen display before export does show all of the requested records. Perhaps relevant source: https://github.com/openemr/openemr/blob/master/interface/reports/collections_report.php#L348

To Reproduce

Reports->Financial->Collections and Aging->Select All->Export Selected as CSV

Expected behavior

Exported .csv contains all selected records.

Client configuration

• Browser: Firefox 109.0
• OpenEMR version: 6.1.0 (1)
