CI-15: run the add-on's test files six at a time, the wall-clock ones alone after

The serial loop summed 3 557 s on SAFETY-125's run and passed the runner's
60-minute cap. The loop moves to .gitea/ci/run-tests.sh: xargs -P 6, longest
files first, then test_loop.py and test_freeze.py (TEST-30 / CI-06) alone on an
idle machine. Same PASS/FAIL lines, CI: echo, tail -40, :ro mount,
PYTHONDONTWRITEBYTECODE=1, GOODWE_REQUIRE_HWSIM=1 and NO test_*.py FOUND guard;
one output file per test file; any failing or unreported file fails the job.
timeout-minutes 70 -> 40, comment corrected. No test file changed.
