Light Themed UI needs redesign

[CODE-MNA]

Complete white background doesn't look good.
Low contrast in NavBar title, buttons are white.
Message Sender input has white inside and doesn't mesh well with outside.

The app was designed for Dark Theme only, if your background is white try switching dark mode on in your browser to use the application in the intended style.

Todo:

Redesign with Light theme so that the app still looks good.
OR
Make dark theme permanent.
