Move progress bar initialization into while loop

Moved progress bar setup from before the while loop to inside the loop on first iteration. This ensures the progress bar is created when rows are actually fetched, even if the initial COUNT query returns 0. Addresses issue where COUNT might return 0 but the while loop still fetches rows to process.
