Summary: Currently the design of `LeftRail` varies a bit between light and dark modes. Additionally washed background color is hard to differentiate from the main background color in comparison to the light theme (See `LeftRail` sidebars toggle buttons background for example). This lead to few contrast related issues, for example the hover effect on the WelcomeScreen elements is not visible in dark mode. The PR tweaks the dark mode theme colors and fixes the unnecessary background of Settings icon in dark mode. I have also spotted that icon `hover` effect is not working when icon has a badge (pure dot or count), I might have an idea how to fix this and I will push another PR for that. 🙂 ## Changelog * tweak dark mode theme colors, improve LeftRail UI Pull Request resolved: https://github.com/facebook/flipper/pull/3335 Test Plan: The change has been testes by running the desktop Flipper app locally from source. ## Preview (before & after) <img width="390" alt="Screenshot 2022-01-24 at 13 37 20" align="left" src="https://user-images.githubusercontent.com/719641/150784627-36e222a8-e53e-4409-ab72-783d4a594f8e.png"> <img width="390" alt="Screenshot 2022-01-24 at 13 46 08" src="https://user-images.githubusercontent.com/719641/150785438-bb496adf-83ab-4b1c-928d-07f4b0098f1a.png"> Reviewed By: antonk52 Differential Revision: D33741513 Pulled By: lblasa fbshipit-source-id: ef187db0725ac2b04c09b7f06823e713b50be88f
