feat(mobile): Various minor performance improvements (#1176)

Browse Source 
* Improve scroll performance by introducing repaint boundaries and moving more calculations to providers.

* Add error handing for malformed dates.

* Remove unused method

* Use compute in different places to improve app performance during heavy tasks

* Fix test

* Refactor `List<RenderAssetGridElement>` to separate `RenderList` class and make `fromAssetGroups` a static method of this class.

* Fix loading indicator bug

* Use provider directly

* `RenderList` refactoring

* `AssetNotifier` refactoring

* Move `combine` to static private method

* Extract compute methods in cache services to static private methods.

* Use `tryParse` instead of `parse` with try/catch for dates.

* Fix bug in caching mechanism.

* Fixed state not being used to trigger conditional rendering

* styling

* Corrected state
