- Create INetworkManager interface for network abstraction - Add EthernetManager for ENC28J60 module using EthernetENC library - Update WiFiManager to implement INetworkManager interface - Update MQTTBridge to use INetworkManager* instead of WiFiManager& - Add heltec_v3_ethernet PlatformIO environment - Uses HSPI bus (GPIO 19/20/47/48) separate from LoRa SPI
