Add the Ansible README and expand prod bootstrap coverage for StorageBox keys, DB labels, DB stack configuration, and act runner setup. Update MongoDB configuration for replica set support and refresh prod roadmap/setup documentation for Swarm labels, StorageBox-backed cert paths, and recovery guidance.
This commit systematically updates all Terraform configurations, including resources, variables, and labels, to use the more generic `app` designation instead of `swarm`. This improves consistency and decouples the infrastructure naming from a specific container orchestration technology like Docker Swarm.
- This commit introduces the Terraform configuration to provision a production environment on Hetzner Cloud, building on the existing test setup.
- Key improvements and new features include:
* **Multi-node clusters:** Scaling to 3-node Swarm application and database clusters for improved resilience.
* **High availability:** Utilizing a Hetzner Floating IP for the application entry point and `spread` placement groups for fault tolerance across physical hosts.
* **Enhanced network security:** Internal management services (RabbitMQ, APISIX, Prometheus, Grafana) are restricted to the application subnet, expected to be accessed via an internal reverse proxy (SWAG).
* **Internal database replication:** New firewall rules enable PostgreSQL replication and MongoDB replica set traffic within the database subnet.
* **Refined test environment:** Updates to align `test` configuration with the new `prod` structure, including a dedicated floating IP and adjusted firewall rules.
* **Configuration standardization:** Environment-specific details moved to `locals.tf` for clarity, with upgraded server types and migration to Rocky Linux as the base image.
- Updates were also made to the latest version of Terraform to ensure consistency in the documentation
