Fix trivial mypy errors

- Add mypy overrides to ignore missing imports for 'can' and 'canmatrix'
- Replace List[int] with list[int] (PEP 585, supported since Python 3.9)
- Add type annotations for untyped variables (var-annotated):
  - lss.py: Queue[bytes]
  - node/local.py: list[Callable] for callbacks
  - node/remote.py: list[SdoClient] for sdo_channels
  - objectdictionary/__init__.py: dict[int, ODVariable] / dict[str, ODVariable]
