The Study Design report is not generated as expected

The Study Design report now appears under the Download Reports sidebar, as expected, when run in Testing mode. Previously, the report failed to generate due to missing data in some columns returned by the system, caused by a recent change to the reporting SQL. The issue occurred because the number of data points did not match the number of expected columns. The underlying code and SQL query were corrected to ensure consistent column and data alignment.
