fix: unblock page rendering when Telegram CDN is unavailable

- Google Fonts: non-render-blocking via media="print" onload trick
- telegram-web-app.js: load only inside Telegram environment
- Telegram SDK init: skip entirely outside Telegram
- Script load timeout: 8000ms → 2000ms for faster deep link fallback
- Email login form: expanded by default (80% of registrations)
