feat(deploy): add production stack for the VPS

Compose file for ikerdemo.cat with nginx as TLS terminator, the three
.NET services, Zitadel and the storage stack. Values come from
deploy/.env.prod (untracked). Adds the frontend image, the migration
script and the Zitadel provisioning for production.
