Replaced `Icepick with Bridge and Android-State`

* IcePick fails on Java 21 (default in Android Studio 2024.2)
* Bridge is the most modern alternative that is currently available. It is backed by ``Android-State`` and can be configured with various frameworks
* In the long term this should be replaced with something better
