Convert XML screens to Compose

The goal is to gradually replace XML based views / screens with composables. The view should be a 1 to 1 conversion with minimal changes to the design. If there are better alternatives in the design system they should be preferred .

Start by reviewing the listed settings entry points and their related fragments, view models, and data stores to identify one self-contained XML screen. Compare each screen with the existing design system and preserve its current behavior and design while replacing its view with composables. The conversion is done when the selected in-scope screen and its related UI pieces no longer depend on the XML view implementation.
