feat: unify QuickInputBar across all apps with locale + deferSearch

- Add `locale` prop to all 6 apps using QuickInputBar
  (todo, contacts, zitare, citycorners, questions, calendar)
- Enable `deferSearch` on apps with create flow
  (contacts, zitare, questions) to match todo behavior
- Pass locale through Calendar's UnifiedBar wrapper
- Questions: default to 'en' locale (English-first app)
