fix(telegram): allow inline_query through the getUpdates filter

The alias module registers an inline-query handler, but pollingAllowedUpdates
listed only message and callback_query. Telegram filters getUpdates on its
side, so inline queries were dropped before reaching the bot — the handler
never ran, and the omission left no log line or error to debug from.

Adds a test tying the list to the kinds actually handled, since nothing else
would catch the next such gap.
