docs(lexer[mypy]) Simplify docs extension imports

why: Mypy was flagging the console lexer fallback import path and stale test ignores even though the docs extensions are loaded from docs/_ext on sys.path.
what:
- replace the console lexer try/except import with the supported top-level import
- remove unused import-not-found ignores from the lexer tests
- keep lexer behavior unchanged while restoring a clean mypy run
