Implement Command History and Logging in Secondary Panel

Current Behavior:

The secondary panel currently displays a static placeholder message indicating that the feature is under development.

Desired Behavior:

The secondary panel should be updated to display a comprehensive history of all Git commands executed through gitx, as well as any relevant application logs, or errors. This will provide users with a clear audit trail of their actions and assist in debugging.

PR Acceptance Criteria:

• All Git commands initiated from the TUI are logged to the secondary panel in real-time.
• Internal application logs from gitx are also captured and displayed in the secondary panel.
• Any errors generated while executing the git commands should also be logged.
• The panel must be scrollable, allowing users to review older command history and logs.
• Attach a screenshot or short video demonstrating the working command history and logging feature.
