Andy Lee 3a1cb49e20 fix: complete Python 3.9 type annotation fixes in backend packages ...

Fix remaining Python 3.9 incompatible type annotations in backend packages
that were causing test failures. The union operator (|) syntax for type hints
was introduced in Python 3.10 and causes "TypeError: unsupported operand
type(s) for |" errors in Python 3.9.

Changes in leann-backend-diskann:
- Convert zmq_port: int | None to Optional[int] in diskann_backend.py
- Convert passages_file: str | None to Optional[str] in diskann_embedding_server.py
- Add Optional imports to both files

Changes in leann-backend-hnsw:
- Convert zmq_port: int | None to Optional[int] in hnsw_backend.py
- Add Optional import

This resolves the final test failures related to type annotation syntax and
ensures full Python 3.9 compatibility across all packages.
