fix: use upstream dongle firmware

Use the common xow_dongle.bin image from the upstream driver for the
GUI session instead of selecting the older 02E6-specific image. Update
the firmware download script and plan to document the same upstream flow.
Keep the extended RX diagnostics used to inspect controller discovery.
