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.
Bind to localhost by default and stop echoing backend errors (which can
embed credentials or low-level details) back over the API and log
broadcast. Validate hotspot SSID/passphrase/channel before writing
hostapd.conf and tighten its mode to 0600 since it stores the WPA PSK.
Restrict WebSocket upgrades to same-origin so a LAN browser can't be
turned into a proxy for the API.
Guard shared state: status reads/writes go through StatusMutex (the
periodic updater races with the toggle and status handlers otherwise),
broadcastToWebSockets no longer mutates the client map under RLock, and
station-event callbacks now run under SafeGo so a panic in app code can't
take down the daemon. Stop channels in hostapd, dhcp, and iwd signal
monitors are now closed under sync.Once to survive concurrent Stop calls.
App.Shutdown is idempotent and waits for the periodic loops before
closing backends, so signal-driven and deferred shutdowns no longer race.

Implement comprehensive configuration management with CLI flags for WiFi interface, device discovery method, and file paths. Add ARP table parsing as an alternative to DHCP leases for more reliable device detection. Improve WiFi scanning to handle concurrent scan requests gracefully.
