Address PR review (dancafc):
- introduce UprnMatch NamedTuple (datatypes/address_match.py) for the
(uprn, address, lexiscore, certificate_number) return, replacing the bare
4-tuple in get_uprn_from_epc_df / get_uprn_from_historic_epc /
HistoricEpcResolver.resolve_uprn. Tuple-compatible, so unpacking is unchanged.
- rename get_uprn_with_epc_df -> get_uprn_from_epc_df (+ callers).
- type resolve_group_ambiguity via a GroupDecision NamedTuple and trim its
docstring.
