ISSUE:

• DateInput2 is missing role="dialog" and a descriptive aria-label on the dialog element

TEST PLAN:

• go to the DateInput2 examples
• open the date picker dialog with a screen reader
• the screen reader should announce it as a "dialog" and include its name, e.g., "date picker"
• examine the HTML — the span containing the date picker should have role="dialog" and an aria-label attribute
