OpenVPN Dashboard Panel Colors

[beornlake]

The OpenVPN dashboard sub-headers appear to be unchanged from the base pfSense theme and don't really blend well with the Palenight color scheme:

If we change this directive at line 601:

.widget .panel-heading {
  background-color: #757575;
}

to something like:

.widget .panel-heading {
  background-color: var(--active);
}

it ends up looking much nicer:

Thanks! I'll try to get this included later tonight
