Khalim Conn-Kowlessar 008c1922c4 feat(epc-prediction): anonymised Tier-1 fixture + builder (ADR-0030)
The committed gate needs frozen, reproducible data without dumping real UK
addresses into the repo. Add:
- harness anonymise_payload + stable_hash: hash street address + cert number
  into opaque, dedup-stable tokens; blank secondary address lines + post_town;
  keep postcode + all component/lodged fields (gov data is OGL). Unit-tested.
- scripts/build_epc_prediction_fixture.py: curate qualifying postcodes (>=1
  SAP 10.2 target + >=2 distinct addresses) from the local scratch corpus,
  anonymise, freeze under tests/fixtures/epc_prediction/.
- The frozen fixture: 15 postcodes / 280 certs / 36 SAP-10.2 targets.
  Verified no plaintext address_line_1 and post_town all blank.
