- AuthContext now stores and exposes sessionToken from telegram-auth
- App.tsx sends session_token instead of tg_id to P2P
- Enables secure cross-app authentication without from_miniapp method
- Remove insecure from_miniapp auth method (telegram_id spoofing vulnerability)
- Implement HMAC-SHA256 signed session tokens (replace weak Base64 encoding)
- Reduce token expiry from 7 days to 24 hours
- Restrict CORS to production domains only (telegram.pezkuwichain.io, t.me)
- Add detailed debug logging for troubleshooting
