fix(pretix): increase memory limit to 6Gi; eventyay nginx sidecar; crowdsec middleware

pretix/standalone runs gunicorn + celery + celery-beat in one container
and OOMKilled at 4Gi. Increased limit to 6Gi, request to 512Mi.

eventyay: add nginx sidecar to serve static files, update health probes
to check a static asset at port 8080, add create-superuser script,
register script in manifest.

crowdsec: middleware fix (previously uncommitted).
