* Introduced `TracingCardState` and `TracingDetailsState`.
Removed all direct viewmodel/livedata access from all nested layouts for `TracingViewModel`.

* Finish TracingDetailsViewModel.kt and TracingCardViewModel.kt
* Remove obsolete dependencies on TracingViewModel.kt and singletons RiskLevelRepository.kt, TracingRepository.kt

* Further cleanup of TracingViewModel.kt, TracingRepository.kt
Still not quite there yet, too many calls going into every direction, back and forth, instead of just top->down, but we are getting there.
We want data flow from business logic code to the UI, keep the UI KISS.
