frontend.set_theme could also set mode from auto to either light or dark for all users.

I like the default dark theme. For reasons I don't want to get into, some browsers that log into my instance of HA clear all user data frequently. This includes cookies and also browser settings. I know that frontend.set_theme can specify the default theme yaml, however it does not set if users should be defaulting to auto/light/dark modes.

I know I can just toss it a theme where no modes are described that looks dark, but I would really like to use the default theme. I tried searching for a reference yaml config for the default themes but have so far failed.

It would be awesome if frontend.set_theme can also define theme mode. Thanks!
