[Feature] Light Certificate automatic renewal

[zyuiop]

The Light Certificate feature is very useful to limit the amount of information you provide to the person that scans your pass, however once the light certificate expires, it is not automatically renewed. This is a usability issue, as everytime you get in a restaurant you have to take the additional step of issuing a new light certificate, and sometimes just end up not doing it.

I think it would be nice that when you enable the light certificate, it stays enabled (and therefore is automatically renewed) until you disable it.
