On RP2040, get_mac_address_raw() only queried WiFi.macAddress(). When ethernet is configured without WiFi, the MAC address was left uninitialized, causing get_mac_address() and get_mac_address_pretty() to return all zeros. This affects device identification (API, mDNS, unique ID). Unlike ESP32 which reads from eFuse (always available regardless of network interface), RP2040 must query the actual network driver. Fall back to ethernet::global_eth_component->get_eth_mac_address_raw() when USE_ETHERNET is defined and USE_WIFI is not.
