Remove unused resolved_ip from PmtuResult dataclass

Removes the unused `resolved_ip` field from the `PmtuResult` model in `src/netsleuth/models.py`, which is a clean-up refactoring for code health. The assignment in `src/netsleuth/probes/pmtud.py` and test instantiations in `tests/test_pmtud.py` were also removed accordingly.
