fix(check): SPDX license string; E501 off in tests (device-types pilot)

The pilot's build warned that setuptools refuses a license table and
License classifiers from 2027-02-18 (PEP 639); check now reports both and
the template builds with setuptools>=77. Recorded device output in tests
keeps its lines, so the template turns E501 off under tests/.
