Channel Activity Implementation for Chat System

Description

This PR introduces the implementation of the Channel Activity feature for the chat system. It focuses on displaying the list of channels and integrating the message screen. The main goal is to allow users to interact with channels and send/receive messages within those channels. It closes issue #311 and a part of issue #275.

Note:
We followed this tutorial: https://getstream.io/tutorials/android-chat/ and did not implement our own screens (ChannelScreen and MessageScreen). This is why we are using another activity.

Given the limited time before the final milestone, we opted for this solution as it is simpler. However, if time permits, we can create our own screens in a separate PR to ensure a consistent design with the rest of the app.

Changes

• Implemented ChannelActivity for viewing and interacting with channels.
• Call a MessagesScreen to display messages within a selected channel and on the accept button of an alert.
• Ensured seamless navigation between the Channel List and Messages Screen.
• Added tests for ChatViewModel to verify channel creation logic.
• Add test to AlertListsScreenTest to validate new navigation and interaction flows.

Screenshots

For the moment, as shown in the following screens, the navigation flow is as follows:

• AlertListsScreen → acceptAlert → MessageScreen → goBack → AlertListsScreen
• AlertListsScreen → sendButton → ChannelScreen → clickOnChannel → MessageScreen → goBack → ChannelScreen → goBack → AlertListsScreen

Description	Screen 1	Screen 2	Screen 3	Screen 4
Send a message by accepting an alert
Once a discussion has begun, you can revisit your messages on the ChannelScreen
