Add unit tests for SdkPacketHandler, SdkRadioInterfaceService, and SdkRadioController edge cases

- SdkPacketHandlerTest: 10 tests covering sendToRadio (MeshPacket and ToRadio variants), sendRaw path for MQTT/XModem, disconnected client handling, and no-op queue methods - SdkRadioInterfaceServiceTest: 14 tests covering device address management, mock transport detection, interface address composition, and connect/disconnect delegation - SdkRadioControllerTest: 3 new tests for sendMessage routing, disconnected sendMessage drop, and requireClient exception Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
