mvc: Decode HTML entities in user privileges, e.g. to not display `&`

[Self-Hosting-Group]

Currently, user privileges (ACL) containing HTML entities are not decoded when displayed. This also affects the plugin, which is renamed by the following PR opnsense/plugins#4629. I also noticed that Dnsmasq DNS & DHCP circumvented the incorrect display by using a different character: https://github.com/opnsense/core/blob/4381fe4903ecbeff19ebd1e04b789628e51124ef/src/opnsense/mvc/app/models/OPNsense/Dnsmasq/ACL/ACL.xml#L3

This raises the question of whether user privileges should also be decoded when displayed, as with the menu items after a253e05.

I meant that seriously/positively because after the last ping, it really went quickly! I love open source devs!
