MethodChannelSmartPrinterFlutter class

Implementation of SmartPrinterFlutterPlatform using MethodChannel.

This class communicates between Flutter and the native Android/iOS implementation via method and event channels. Each printer action (like scanning, printing, cutting, etc.) is invoked through specific channel methods.
