Interface: SerialTransport

Physical serial transport parameters (UART / USB-serial).

For Bluetooth SPP printers — even though most platforms surface the RFCOMM channel as a /dev/rfcomm or COM port — use the bluetooth-spp key instead so the runtime picker can present it as "Bluetooth" rather than "Serial port".
