fix(bar): Ensure SystemMonitor temperature is fully visible

In the vertical bar layout, the temperature text in the SystemMonitor
widget (e.g., "55°C") could be truncated due to the widget's fixed
width.
  This commit resolves the issue by applying a dynamic scale
transformation to the text component.
