fix(address): normalize SECTORUL + etaj in addr_match, fix Oracle duplicate addrs

- _addr_match / addrMatch: add SECTORUL\s*\d* branch to strip sector
  number; add (?:\b|(?=\d)) to catch glued keywords (sc1, ap94);
  include etaj field in rStreet concat
- database.py: replace duplicate addr_match impl with import from sync_service
- import_service.py: short-circuit billing addr Oracle call when
  billing == shipping (avoids duplicate address creation)
- PL/SQL: normalize MUNICIPIUL BUCURESTI → BUCURESTI SECTORUL X before
  TIER 1; resolve id_localitate before search; TIER 1 now matches on
  id_loc instead of text locality
- Add scripts/cleanup_duplicate_addresses.sql for manual prod cleanup
- Add 5 new tests: sectorul, keyword+digit gluing, etaj, short-circuit
