Tapping user avatar or network indicator sends a test signal with
geo data. Backend formats it as "Тест от username" (🧪) instead of
"Сигнал" (🚨). Only active after login on main screen.

Only @tutlot.com emails allowed for registration (checked server-side,
invisible to frontend inspect). Wrong domain → scary message + IP
violation tracked. 5 violations → IP permanently blocked from login
and registration. Block screen with OK button on frontend.

Login now requires login/email + password verified against DB via
/api/auth/login. Only approved registrations can access the app.
Signal endpoint accepts JWT Bearer tokens alongside legacy api_key auth.
Old UUID-only registration flow removed from frontend.
