Feat: Implement Dark Mode

[Asymtode712]

Is your feature request related to a problem? Please describe.
I'm always frustrated when using the application in low-light environments as the bright interface strains my eyes. The current light mode is not suitable for nighttime use or dark environments.

Describe the solution you'd like
I would like the application to have a Dark Mode option. This mode should invert the color scheme to use darker backgrounds and lighter text. Ideally, it should be a toggle switch available in the settings or main interface, allowing users to switch between Dark Mode and Light Mode seamlessly.

Additional context
Will add a toggle mode to toggle between light and dark mode
