refactor(document-picker): downgrade listbox ARIA roles; fix unique listboxId

role=listbox + role=option without arrow-key navigation is misleading — the
WAI-ARIA combobox pattern requires aria-activedescendant handling that isn't
implemented. Downgraded to plain <ul>/<li>; input keeps role=combobox +
aria-controls pointing to the list id.

listboxId was a module-level constant so two simultaneous instances would share
the same DOM id. Fixed with a <script module> counter.

Updated spec queries from getByRole('option') to getByText() — tests behaviour,
not the ARIA implementation.
