feat: Add automatic Address1, Address2, and FullAddress properties to Address model

- Add Address1 property that builds street address from components and handles PO Box addresses
- Add Address2 property that builds unit/apartment line from subaddress components
- Add FullAddress property that combines all components into formatted string
- Properties are computed on-demand and always available after parsing
- Add comprehensive test suite with 16 new tests covering various address types
- All code passes ruff and mypy checks with 100% backward compatibility
