Remove numbered labels from error and change markers

- Remove red_labels parameter from draw_boxes_multi() function
- Remove label rendering code that added numbers to difference boxes
- Clean up function calls to remove unused labels parameter
- Difference boxes now show without numbered labels for cleaner display
- Maintains all other functionality (red boxes for differences, cyan for misspellings, green for barcodes)
