feat: Implement logo printing to thermal printer and add loading indicator
• Replace StrukTextGenerator with EscPosPrintService to support image printing • Add loading indicator during print process to prevent UI freeze • Fix Uint8List type issues for printer compatibility • Improve error handling with proper state management • Users can now print selected store logo on thermal receiptsmaster
