Ruff flagged duplicate RESOAPIError class/imports, unused imports, and a
duplicate test class in the RESO adapter and saved-search-notifications
modules; mypy flagged the duplicate class plus missing type annotations
and Dict[str, Any] mismatches in reso_adapter.py. Also drops an unused
dataclasses import in tax_strategy.py flagged by ruff.
