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.

Privacy/stigma layer on top of the authenticated Supabase session — re-auth on
open so nobody but the user can open Rebreak. Not a login replacement.
- expo-local-authentication; NSFaceIDUsageDescription in app.config
- stores/appLock.ts: persisted `enabled` pref, in-memory `locked`, device-
capability check (`available`), device-passcode fallback on biometric failure
- AppLockGate wraps the root layout: locks immediately on `background` (not
`inactive` → app-switcher peek doesn't lock), renders LockScreen while
`enabled && locked && session`
- LockScreen: dark brand screen, auto-prompts on mount + on return from
background, "Abmelden" escape hatch (clears session → fresh login next launch)
- Settings: new "Sicherheit" section, native UISwitch; enabling requires a
successful biometric prompt first; row disabled + explained when device has no
biometrics/passcode
- de/en strings
Per product call: the lock gates the whole app incl. SOS (SOS already requires
an authenticated user, so there's no unauthenticated path to carve out).
Cold-start: appLock init blocks the splash → `locked` is set before first paint,
no flash of unlocked content. ios/ is gitignored so EAS prebuilds the new module.
