Repair struphy-install action

• do not use venv in struphy-install action; prepare Python env instead
• try to make MacOS workflow actually do something
• clean up PR tests
• run PR tests on scheduled week-end pipeline

They are not skipped, as I did not eliminate them from the PR workflows. I commented the non-MPI tests from the weekend pipeline (reusable-testing), just for now, maybe we add them back later.

Oh, I see that now. I misunderstood this when reviewing on my phone
