Constants.platform.ios.model returns only generic "iPhone" instead of
"iPhone 15 Pro" + osVersion was unreliable. Switched lib/deviceId.ts to
expo-device which exposes Device.deviceName ("iPhone von Chahine"),
Device.modelName ("iPhone 15 Pro") and Device.osVersion ("26.4.2") on real
devices. Constants stays as fallback for Simulator/Web.
Backend touchDevice + auto-register already backfill these fields from the
x-device-* headers (commit 60f608d) — but only with proper Frontend values
which Constants couldn't provide.
Requires new native build (versionCode 8) since expo-device is a native
module — current TestFlight build (7) still ships with old Constants logic.
