Add conditional rendering for optional fields

[fergusfinn]

Description

Add proper conditional rendering for optional fields to avoid rendering empty elements.

Problem

In UsersGroups.tsx (lines 486-488):

<p className="text-sm text-doubleword-neutral-600 mb-4 break-words">
  {group.description}
</p>

If description is undefined or empty string:

• Renders empty <p> tag with margin
• Creates awkward whitespace
• Inconsistent spacing between cards

Solution

{group.description && (
  <p className="text-sm text-doubleword-neutral-600 mb-4 break-words">
    {group.description}
  </p>
)}

Other Occurrences to Check

Search for optional fields that might be undefined/empty:

• User display names
• Model descriptions
• Endpoint descriptions
• Any optional text fields

Files to Change

• dashboard/src/components/features/users-groups/UsersGroups/UsersGroups.tsx
• Review other components for similar patterns

Impact

• Cleaner DOM (fewer empty elements)
• More consistent spacing
• Better accessibility (no empty elements for screen readers)
