Simplify phonon get_supercell_size() and test clean up (#783)

* simplify phonon job get_supercell_size()

* remove torch.set_default_dtype(torch.float32) from test_phonon_wf()

should be obsolete now with revert_default_dtype context manager

* include method (vasp|force field) in phonon flow test names

* simplify test_phonon_wf_force_field with intermediate variables

* remove duplication by using si_structure pytest fixture

* ruff fixes
