🎯 Goal

Add utils.channelListConfig.channelItemMutedLayoutStyle config option to change the channel list item muting view style.

📝 Summary

• Adds utils.channelListConfig.channelItemMutedLayoutStyle to configure the mute view style
• Disables channel pinning feature by default in the Demo App

🛠 Implementation

Mute styling:
There is quite a lot of inconsistency in our SDKs, where different platforms have at least 3 styles of rendering when a channel is muted. This PR provides a config so that you can switch easily between the 3. It does not make sense that every customer needs to rewrite the Channel list item whenever they want consistency in the muted styling.

Demo App Pinning:
A flag was added to the AppConfiguration to enable/disable the channel pinning feature. By default, it was enabled. This was a bit dangerous because it meant that while testing the DemoApp we were not using the SDK code, but only the Demo App code for the channel list item view. So we would not catch potential regressions.

🧪 Manual Testing Notes

All scenarios are covered by snapshot tests.

The Demo App now follows the same style of Android Compose components. (Muted icon after the channel name)
