kin: BATON-SEC-001 pre-commit hook + httpx logging hardening

1. .pre-commit-config.yaml — local pygrep hook блокирует коммиты
   с токенами формата \d{9,10}:AA[A-Za-z0-9_-]{35} (Telegram bot tokens).
   Проверено: срабатывает на токен, пропускает чистые файлы.

2. backend/telegram.py — три функции (send_registration_notification,
   answer_callback_query, edit_message_text) логировали exc напрямую,
   что раскрывало BOT_TOKEN в URL httpx-исключений в journalctl.
   Заменено на type(exc).__name__ — только тип ошибки, без URL.
