System and Application Theme

Is your feature request related to a problem? Please describe.
System theme and Enatega Application theme is contradicting with each other.

Describe the solution you'd like
When the user install the enatega application and uses it, the application should be able to pick whichever theme system is already using.

The issue names no files, tests, or entry points. Start by locating the application's theme configuration and how it detects the system theme; the work is done when the application follows the user's existing system theme without contradicting it.
