"""Tests for Telegram username (non-numeric) chat_id handling (#13206).

When ``TELEGRAM_HOME_CHANNEL`` is an ``@username`` rather than a numeric chat
ID, webhook/cron deliveries that fall back to the home channel used to crash
with ``ValueError: invalid literal for int()`` because the adapter coerced
every chat_id with ``int()``. Telegram's Bot API accepts both forms, so the
adapter now normalizes instead of force-casting.
