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.
When signing up, the user is given a pin code which they send to a
telegram bot. This provides user verification, but more importantly
allows the bot to message the user, as the Telegram API requires the
user to interact with the bot before it can do the opposite.
The bot should recognize the correct language, but a /lang command is
also provided to change it.
The verification process is pretty much functional but ui is still
broken, and it isn't properly integrated yet.
