refactor(host): remove FT601 references from radar_dashboard, smoke_test, and docs

Replace FT601Connection with FT2232HConnection in radar_dashboard.py and
smoke_test.py. Both files had broken imports after FT601Connection was
removed from radar_protocol.py. Also update requirements_dashboard.txt
(ftd3xx -> pyftdi) and GUI_versions.txt descriptions.
