Few things

- Finished working with the card fusions - Added the GUI part to access the data - Cleaned up a bit of the code, separated a few things from the SettingsScreenControllerImpl.kt into separate classes. - Removed a few LaunchedEffect in exchange of Flows (UI now updates automatically when an action happens)
