fix: correct type annotations for ids parameter and test assertions

- Change ids parameter type from list[int] to list[str] in dicttoxml function
- Update convert_dict and convert_dict_parallel to accept list[str] | None
- Fix test to use string list instead of int list for ids
- Add None check in test_parallel.py before type narrowing result_bytes
