UI Bug: NextDNS Mac app's "Enabled" slider should be Blue when On

This one is very minor:

It's odd that the Enabled / Disabled slider in the NextDNS Mac app (2.1.3 26) is not "Blue" when enabled. As a result, it looks disabled at first glance.

With the slider control in macOS, Blue = On. (See the "WiFi" popover screenshot for comparison.)

Thanks for looking at it!
