fix(desktop): name the connected Telegram bot after QR setup

After a QR apply the success toast only said the gateway was restarting,
and reset() wiped the bot name, so the Quick setup card fell back to the
"already configured, will replace" warning with no sign of which bot was
just connected.

The toast now reads "Connected: @bot · Telegram saved; gateway
restarting…", and the card keeps a Connected badge with the @bot handle
in place of the replace warning until the next setup starts.
