fix(ui): add dark mode variants to version status styles

[jamofer]

Summary

• Add dark: background variants to active (dark:bg-blue-950/40) and released (dark:bg-green-950/40) version status styles — previously used light-only backgrounds that were unreadable in dark mode
• Add dark: icon color variants (dark:text-blue-400, dark:text-green-400) for better contrast
• Add explicit border-gray-200 dark:border-gray-800 to version row <li> elements — border was nearly invisible in dark mode
