Fix lint: black formatting and mypy assignment override

- black: long compilation_bindtemplate property line wrapped onto 3 lines.
- mypy: parent SQLCompiler annotates bindtemplate and compilation_bindtemplate
  as str, and a property is a different type for static analysis (runtime
  behavior unchanged — descriptor returns str on access). Add
  # type: ignore[assignment], consistent with the # type: ignore pattern
  already used in base.py:52 for preparer override.
