Barcode generator: rfct, ux improvements, implement EAN-8.

[msvsergey]

What's new

• Code is totally refactored (removed similar functions for every digit, increased readability by introducing enum and constants for view modes/menu items, other improvements).
• Implemented EAN-8 (issue)
• UX improvements: align elements, correctly handle ok and back buttons.

Verification

• Make sure both UPC-A and EAN-8 are working correctly.

Could you add EAN-13 type barcode gen? It's the most used for everything
