Feat: Add live log monitoring tab to UI

Introduces a new "Monitor" tab in the `BuildFFUVM` UI to display live log output from the build process.

When a build is started, the UI now automatically switches to the Monitor tab. It tails the main log file in real-time and displays the content in a list view, which auto-scrolls as new entries appear.

This provides immediate visual feedback on the build progress and any errors without needing to manually open the log file.

Additionally, this change adds a Ctrl+C keyboard shortcut to copy selected log lines from the monitor view to the clipboard.
