Restore a visible focus indicator on the table target.

After successful removal, the dialog calls focus() on this tabIndex={-1} element. outline-none removes its outline, and no focus ring is defined. Add a focus ring so the focus move remains visible.

Suggested change
className="bg-white dark:bg-gray-800 rounded-lg shadow-lg overflow-hidden outline-none"
className="bg-white dark:bg-gray-800 rounded-lg shadow-lg overflow-hidden outline-none focus:ring-2 focus:ring-blue-500"

In `@src/routes/admin/roles`.$roleId.tsx at line 393, Update the dialog target’s
className to retain the existing styling while adding a visible focus ring for
the element focused after successful removal; do not leave the focus indicator
suppressed by outline-none without an equivalent focus style.
