Greptile Summary

This PR improves the visual appearance of the disabled state for the v2 Checkbox component by adding cursor-not-allowed and opacity-40, and darkens the default base background from bg-mineshaft-600 to bg-mineshaft-700.

• Disabled state: replaces the old flat bg-bunker-400 override with opacity-40 for a more universally apparent "dimmed" look and adds the cursor-not-allowed cursor.
• Base background: shifts from bg-mineshaft-600 to bg-mineshaft-700, providing a slightly higher-contrast default that better separates unchecked checkboxes from their surroundings.

Confidence Score: 4/5

Purely visual Tailwind class changes with no logic impact — safe to merge.

The change only touches CSS utility classes on a single presentational component. The one minor concern is that the previous disabled override explicitly neutralized the hover transition, but the new version omits this, leaving the base hover class active even when the checkbox is disabled.

No files require special attention beyond the hover behaviour noted in Checkbox.tsx.
