fix(web): include ward in address display across card views

- property-card.tsx: add ward between address and district in both
  card (line 189) and list (line 95) layouts
- transfer-listing-card.tsx: conditionally prepend ward to
  district/city when ward is non-null
- property-card.spec.tsx: update address test to assert ward is shown,
  add list-layout ward regression test (21/21 pass)

Standard format: {address}, {ward}, {district}, {city}
Compact (project-card, industrial-listing-card): district/city only —
intentional; ProjectSummary has no ward field.
