Lbry-desktop: Don't allow dark mode with automatic night mode enabled

[tzarebczan]

The Issue

If you enable automatic night mode, the theme selection should not allow the dark theme to be chosen as it overrides the setting. Not sure about disabling the theme selection completely - right now it makes sense because there is only 1 option, but in the future when we have more, a user may want theme X and have night mode enabled.

Probably better to disable the night mode setting once the dark theme has been selected than to disable the theme if night mode is selected.

Going to re-open this because you can select automatic dark mode while dark is selected, which forces the app to stay in dark mode.
