#794: Telegram-Client-Anmeldung ueber die WebUI
Code und 2FA-Passwort wurden nur im Desktop-Dialog abgefragt; eine Instanz ohne Fenster liess die Anmeldung aus. Jetzt haelt die Instanz die Frage (TelegramLoginBroker), die Einstellungsseite beantwortet sie. Die Anmeldung laeuft im Hintergrund, damit die HTTP-Flaeche, ueber die der Code kommt, nicht auf ihn wartet. Eine offene Frage verfaellt nach 15 Minuten.
