ci: configure mypy to handle untyped typer decorators

- Add mypy overrides for meter_reader.main module
- Disable untyped-decorator and import-not-found errors for main.py
- This allows using typer without type stubs while maintaining strict typing elsewhere
- All tests (82), linting (ruff), and type checking (mypy) pass successfully
