server-side.
Generic and reusable by the next suite: setup_testinstance.php (--setup/--verify,
delegating the rebuild to paolos db_setup.sh), tasks/db.js, tasks/sshTunnel.js,
tools/dbCheck.js and cypress.config.js carry no suite-specific knowledge. A suite
adds tools/checks/<name>.js, suites/<name>.js and its own task file.
Fixture state resets over a direct Postgres connection through an SSH tunnel the
runner opens itself.
Tests: 37 passing, 5 pending, 1 failing. Pending are opt-in (Freigabe sends
real mail; the Frist config is off). The failing spec is left red on purpose: it
documents that getLvGesamtNoten filters freigabedatum < NOW(), so the read path
hides un-freigegebene notes while the write path uses the unfiltered getter. Not really certain if that is a feature or a bug;
Working on more actual testsuites now that the setup is running as intended;
