Fix preview padding to match actual template padding

[utdevnp]

The preview area does not reflect the exact padding as set in the template, leading to discrepancies between the preview and the final output.

Steps to reproduce:

1. Set a specific padding value in the template settings.
2. Observe the preview area.
3. Notice that the padding shown in the preview does not match the actual padding applied to the template.

Expected behavior:

• The preview should accurately display the exact padding as configured in the template settings.

Additional context:

• Ensure the padding is consistent across all browsers and devices.
• Check both the CSS and any logic that renders the preview area.
