- Updated KVStorageHandler interface to use std::string instead of char* for key-value operations. - Enhanced NVSStorageHandler to utilize ESP_LOG for error and info messages instead of printf. - Refactored WifiHandler to manage WiFi credentials using JSON format for better structure and storage. - Replaced raw pointers with std::unique_ptr in WifiHandler and NetworkHandler for automatic memory management. - Removed unused TouchHandler and EInkTouchHandler classes to clean up the codebase. - Adjusted CMakeLists.txt to remove unnecessary include directories. - Updated lv_conf.h to enable FreeRTOS and gesture recognition features.
