Anonymous users must not get cookies or session store entries, so a
CSRF token for /login is not possible. Instead, every unsafe request is
checked statelessly via Sec-Fetch-Site, falling back to Origin. Requests
without both headers are not from a browser and are accepted. The
expected origin comes from the new MAX_ORIGIN setting, which is required
outside of debug mode.
Further CSRF changes:
- Do not delete the CSRF token on a failed check. It added no security,
but invalidated forms in open tabs and could be triggered cross-site.
- Treat HEAD and OPTIONS as safe methods.
Keep the login page free of sessions:
- Show login messages via ?msg=login_required|logout (fixed keys only)
and the login error via the template context instead of flash().
- Only send the session deletion cookie if the client sent a cookie.

- scripts/prod: entrypoint, db-setup and schema.sql shipped in the image
- scripts/dev: seed/clear db, psql and cleanup, run natively in the
devcontainer instead of via docker-compose
- move setup.cfg to the repo root so linters pick it up
- Makefile targets run directly in the devcontainer
