fix: improve PDF417 barcode generation and data handling

- Fix newline corruption: URL-encode hub3aText to prevent browser form submission from converting \n to \r\n
- Align with HUB3A specs: Set error correction level to 4 and pixel size to 4x3 for better barcode scanning reliability
- Fix barcode sizing: Add responsive width constraints (max-w-[35rem], sm:max-w-[25rem]) across all barcode displays
- Update package dependencies: Remove peer dependency flags
