Subject: [PATCH] test(person): rewrite PersonTypeahead test with behavioral
 assertions

Replaces 3 setTimeout sleeps with vi.waitFor on listbox / aria-expanded
state and converts 2 .not.toThrow smoke tests + 1 vacuous expect(true)
into assertions about the input remaining usable after fetch errors
and Escape on a closed dropdown being a no-op.
