autoresearch iter 20: give the telegram poller a real long-poll window

Browse Source 
telebot types LongPoller.Timeout as time.Duration and sends
int(timeout / time.Second) to getUpdates, so the literal 10 meant ten
nanoseconds: Telegram received timeout=0, long polling never held the
connection, and the adapter polled the Bot API in a tight loop instead.
Use 10 seconds and extract the settings so the conversion is asserted.

The adapter also has no media temp-dir cleanup (downloadMedia creates an
MkdirTemp per attachment and nothing removes it); that is left as a separate
change rather than bundled here.
