Improve samples UI

[leny62]

Overview

This PR removes all references to SimpleConsoleUI from the Libp2p /Chat Application sample. The application now exclusively uses the modern Terminal UI (TerminalUI), streamlining the codebase and ensuring that we maintain a consistent and feature-rich user experience.

Changes Made

• UI Initialization:

  • Updated the initialization logic to exclusively use TerminalUI.

• ChatProtocol Configuration:

  • Modified the configuration method so that the ChatProtocol is bound only to the TerminalUI adapter.

Motivation & Benefits

• Modern User Experience:
  The TerminalUI delivers a multi-panel interface with 3 tabs: chat, peers (connected peers) and logs

Testing & Verification

• Listener and Dialer Modes:
  Confirmed that both modes work seamlessly with TerminalUI.

• UI Functionality:
  Verified that status updates, peer additions, and graceful shutdown via the TUI (using exit shortcuts like ESC and Ctrl+C) work as expected.

• Logging:
  Ensured that all logging, especially error handling in case of initialization failures, is effective and informative.

Related Issues

• Closes #57
