Slice 1/6 of the postcode_splitter refactor (Hestia-Homes/Model#1100). Introduces the pure-domain foundation under domain/, with no AWS, Postgres, or pandas. UserAddress is a frozen dataclass that sanitises its postcode in __post_init__ via the canonical sanitise_postcode helper, and iter_postcode_grouped_batches preserves the legacy splitter's batching invariants (group-by-postcode in insertion order, never split a group, oversize single-postcode groups dispatched whole, final flush). Updates UBIQUITOUS_LANGUAGE.md so the User Address term covers both the dataclass sense (preferred in domain code) and the raw upstream-string sense.
