telegram: Fix UI and store useful Telegram info

Creation now works, and language preferences made before signup are
kept. telegram file storage now uses the Jellyfin ID as a key, which
makes much more sense. Also added radios to select preferred notification
method (email/telegram) as well, which the admin will soon be able to
change also.
