Search before asking

• I had searched in the issues and found no similar feature requirement.

Use case

As a developer who's every program he uses is in dark mode, going into the super white and bright devlake ui is a bit harsh on the eyes.

Description

Enable switching between white mode and dark mode in the ui, like in docusaurus.
