Jun-te Kim 7aea692521 historic EPC: read via infrastructure/s3, not the utils.s3 utility
HistoricEpcS3Repository reached into utils/s3.py (read_csv_gz_from_s3 +
parse_s3_uri), the legacy utility that self-constructs boto3 inside free
functions. The other S3 repositories deliberately depend on the
infrastructure/s3 layer instead (UnstandardisedAddressListCsvS3Repository
injects a CsvS3Client). Bring historic EPC into line.

- Add GzipCsvS3Client(S3Client) in infrastructure/s3: read_csv_gz(key) ->
  DataFrame (get_object + gzip decode).
- Inject it into HistoricEpcS3Repository; the bucket lives in the client and
  the repo only builds the per-postcode key + maps rows (no S3/HTTP code).
  Add with_default_s3_client(s3_root) for composition roots.
- Update main.py and the match_addresses_for_postcode seam to the factory.
- Repo tests inject a real GzipCsvS3Client over a controlled boto stub
  (exact key assertions + AccessDenied); add a moto-based client test and a
  factory test covering s3_root -> bucket+key.
