Chat Window

User story

As a user, I want the main chat page to feature a chat window as the primary content. The chat window should occupy most of the page and display messages from top to bottom. Additionally, scrolling functionality should be implemented when the messages exceed the height of the chat window. For now, mocked messages can be used.

Acceptance criteria

• The main chat page contains a chat window as the primary content.
• The chat window occupies a significant portion of the page.
• Messages in the chat window are displayed from top to bottom.
• When the messages exceed the height of the chat window, scrolling functionality is enabled.
• (Optionally) the external chat library could be integrated.
