Log.print used developer.log with no kDebugMode guard, so release
builds emitted wallet JWTs, the HMAC secret, phone numbers and full
API responses to os_log/logcat on the user's device. Both the rider
and driver apps were affected.
Also removes a hardcoded test-account condition in the rider login
flow that skipped the entire FCM-token/fingerprint comparison — and
therefore the device-change OTP — for one email address.
