Address

Structured address capture with manual entry and Google Places autocomplete. Lives today as AddressFieldset in apps/public/onboarding/components/.

Extraction deferred. This component depends on the Google Places script loader, the address normalizer at apps/public/onboarding/lib/address.ts, and the autocomplete-menu CSS — moving them all to packages/ui deserves its own pr. Tracked as a follow-up under the design language formalization card.
