This commit introduces a reordered and renumbered set of setup documentation files to better reflect the deployment stages for both test and production environments.
Key changes include:
* A new `setup-vs-roadmap-map.md` file to provide a clear mapping between roadmap tasks and their corresponding setup phases.
* Significantly expanded Ansible bootstrap documentation for both test and production, detailing Docker, Swarm, security hardening, and StorageBox SSH key management roles.
* Formalized database Docker and Swarm cluster setup instructions for test and production, including explicit steps for Swarm worker integration of DB nodes.
* Updated roadmap documentation (`roadmap/prod-env/*`) to align with the refined setup, incorporating correct private IP addresses for Swarm joins, new node labels, and floating IP usage for GoDaddy DNS records.
- Add `hetzner-sizing-report.md` defining data-driven server type recommendations for test and prod environments.
- Update Terraform configurations to align with the recommended `CPX` server types and refine firewall rules for Docker Swarm and database interactions.
- Introduce comprehensive documentation and stack files for:
- Single-node PostgreSQL/MongoDB deployment on a test DB worker node.
- High-availability 3-node MongoDB replica set and Patroni+etcd PostgreSQL cluster for production.
- Enhance Ansible bootstrap roles with SELinux disabling, fail2ban configuration, and StorageBox SSH key management for CI/CD.
- Reorganize and rename setup documentation files for improved structure and clarity.
