[IMP] lunch: add possibility to notify users on lunch arrival

There was no way for the lunch manager to notify users that their meal
had arrived prior to this commit besides manually sending a message to
the concerned users.
There now is a dedicated button after the order has been confirmed by
the lunch manager to send notifications.
