🐛 fix(installer): align with tox 4.59 API changes (#366)

The scheduled check has been red since tox 4.59 landed
(https://github.com/tox-dev/tox-uv/actions/runs/31787082911):
tox-dev/tox@7be33b8 widened `Pip._install_list_of_deps` to
`Sequence[Requirement | Package]`, so ty reports the narrower override
in `_installer.py` as incompatible, and `ToxEnv.name` now reads
`conf.get("env_name", str)`, so `test_get_python_abs_path_with_impl`
priming only `conf.__getitem__` hands a MagicMock to
`PythonSpec.from_string_spec`. Widen the override to `Package`, drop the
`ty: ignore[no-matching-overload]` that ty now flags as unused, and
patch `name` with a PropertyMock in the test the same way its neighbour
does, so it stays independent of how tox resolves the env name.
