Fix increasing unread count for muted channels

[VelikovPetar]

🎯 Goal

We are incorrectly increasing the channel unread count locally for muted channels on message.new and notification.message_new events. This PR fixes that behaviour and aligns the behaviour to iOS and follows the documentation: https://getstream.io/chat/docs/android/muting_channels/

Additionally, it fixes a bug where the channelState.muted state was not initially set properly after QueryChannels.

Resolves: https://linear.app/stream/issue/AND-736/analyse-wrong-unread-count-for-muted-channels

🛠 Implementation details

• Prevents increasing of the local unread count for the channel if the channel is muted
• Syncs the mute state when the ChannelLogicState is initialised, to ensure that the correct state is present at all times

🎨 UI Changes

Before	After
before.mov	after.mov

🧪 Testing

1. Mute a channel
2. Write messages in the same channel from a different user
3. Ensure the unread count is not increased (verify by reloading the channel list)
