What's new in this PR?

Issues

We don't have a way in the app to quickly navigate to the bottom of the messages list, aka. jump to last message.

Solutions

Implement it by using Scaffold FAB embedded into messages list component, taking at the same time advantage that MessagesList component, passed down is a composable, so I was able to have it for free for Disabled message composer as well.

Using the outer scaffold was not an option after many tries, because it also considers the attachment options menu, making it almost impossible to customize the position dynamically.

Looks very nice 🧑‍🍳
Just one question: do we have 2 scaffolds in the composable tree? I think we can achieve similar functionality with adding box with some ime padding for this button? 🤔
