[Due for payment 2025-02-28] Replace `react-native` Animated API with `react-native-reanimated`

[blazejkustra]

Full proposal here.

Replace Animated API with Reanimated, which runs animations on the UI thread (instead of JS thread), ensuring great performance. Reanimated integrates deeply with react-native-gesture-handler (used throughout our app), offers advanced animations, and supports higher frame rates — exceeding 60fps.
