Show USB serial ports first with two-line port selector - #371

Sort serial ports so USB adapters (ttyUSB/ttyACM) come before hardware ports, both in SerialTransport.list_ports() and the port dropdown. Add SerialTransport.list_port_info() providing device descriptions from pyserial, or from /dev/serial/by-id symlink names when running sandboxed. Rework SerialPortAdapter into a two-line combo row mirroring the WCS selector: device path plus a dimmed description line. A configured port that is not currently plugged in is pinned to the top of the list instead of being appended at the end.
is_usb_serial_port() treats every port as USB on non-POSIX systems, so the new sorting and port info tests must pin os.name to posix when exercising Linux-style /dev/tty* paths.
The adapter sorts via is_usb_serial_port(), which treats every port as USB on non-POSIX platforms. Patch os.name alongside the port scan so the Linux-style fixtures sort as expected on Windows.

Summary
SerialTransport.list_ports()and in the port dropdown, with natural ordering within each group (ttyUSB2 before ttyUSB10)SerialTransport.list_port_info(), which provides device descriptions from pyserial metadata on regular systems, or from/dev/serial/by-idsymlink names when running sandboxed (Snap), where pyserial cannot enumerate safelySerialPortAdapterinto a two-line combo row mirroring the WCS selector: device path on the first line, dimmed USB description (e.g. CH340) on the second. The model holds raw device paths, so no label/value mapping is neededTest plan
