Fix barcode format and improve scannability

- Changed sequential numbering from slash to hyphen format (TEST-ORD-004-0001)
- Increased horizontal barcode bar width from 0.25mm to 0.30mm for better scanning
- Increased vertical barcode bar width from 0.15mm to 0.30mm for reliable readability
- Changed from 3-digit to 4-digit padding for piece numbers (0001 instead of 001)
- Removed aggressive scaling that was distorting barcode bars
- Barcodes now use optimal settings for thermal printers and handheld scanners
