Bug: existing devices registered before Frontend started sending x-device-name/
x-device-model/x-device-os headers stayed with NULL fields forever — DeviceLimit
sheet shows only platform label ("iPhone" without iOS version, no name).
Fix:
- touchDevice() now accepts optional { name, model, osVersion } and updates
these fields when headers are provided (existing-row backfill).
- requireUser auth middleware reads URL-encoded x-device-* headers + passes
them to both touchDevice() (existing) and registerDevice() (auto-register).
After deploy: next authenticated request from updated client backfills the
device record automatically (throttled per TOUCH_THROTTLE_MS = 1×/min).

- Schema: lyraVoiceId stays, new os_version column on user_devices (Migration 20260515)
- registerDevice() merge-heuristic: if existing record matches userId + same name +
same model + lastSeen < 30 days, update existing instead of inserting new.
Fixes iOS IDFV-reset creating phantom devices on Recovery-Restore.
- register.post.ts: accepts osVersion in body, maps isCurrent in error-path payload
- New util testUser.ts: isTestUser(email) — explicit allowlist for charioanouar@gmail.com
plus existing @rebreak.internal suffix
