Add spacing between input fields in form

[Copilot]

This PR addresses the issue of insufficient spacing between input fields in the Virtual Machine Selector form, making it more readable and user-friendly.

Changes

Added a row-gap property to the #selector CSS grid to provide 10px of vertical spacing between form rows. This is a minimal single-line change that significantly improves the visual layout of the form.

#selector {
    display: grid;
    grid-template-columns: 180px auto;
    row-gap: 10px;  /* Added this line */
}

Screenshots

Before

The input fields were tightly packed with no spacing between rows:

After (Light Mode)

Clean 10px spacing between each form row:

After (Dark Mode)

The spacing improvement works correctly in dark mode as well:

With Data

Form remains fully functional with improved readability:

Testing

• ✅ Form loads correctly with improved spacing
• ✅ All input fields remain functional
• ✅ Form submission works as expected
• ✅ Spacing looks good in both light and dark modes
• ✅ No layout issues or visual regressions
