station: Default device type to "unknown" and propagate DHCP hostname

Browse source 
GuessDeviceType silently returned "mobile" for any device whose hostname
or MAC OUI didn't match a known pattern, so the UI labelled every
unidentified device as a phone. Default to "unknown" instead and broaden
hostname matching (pixel/galaxy, thinkpad, imac/-pc, QEMU OUI).

The hostapd backend was also dropping DHCP hostnames on the floor: the
correlator only forwarded MAC->IP, and convertStation hard-coded the
hostname to "". Replace UpdateIPMapping with UpdateLeaseInfo that carries
both maps so hostnames flow through to ConnectedDevice.Name.

Frontend gains a "Sans nom" fallback when no hostname is available and
French labels for the device-type badge.
