Fix or disable light mode

[simonalveteg]

I never use light mode, and the app has been designed using dark mode. I always have my phone in dark mode so I never notice how shit the light version of the app is.

It would be annoying to fix all the colors for light mode and make it look good, especially since I'll never use it myself.

If I disable light mode I won't have to maintain two different color schemes, and can spend more time on other features.

Will probably disable light mode at some point.
