The Add Person dialog wrapped its form content in a plain <div>
instead of DialogContent. When the form is tall enough, the
dialog extends beyond the viewport with no way to scroll,
cutting off the contract end date field.
Replace the raw <div> with DialogContent which provides
overflow-y-auto and a maxHeight constraint, matching the
pattern used by all other dialogs in the codebase.
