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 introduces the foundational Ansible playbooks, roles, and configurations for automated provisioning of both production and test environments.
Key capabilities include:
- **Base System Setup:** Common packages, timezone, chrony, and hostname.
- **Security Hardening:** SELinux disable, SSH configuration, `dnf-automatic`, `fail2ban`, `firewalld` setup, and `journald` log limits.
- **Docker & Swarm:** Docker installation and configuration, Docker Swarm initialization/joining for managers and workers, overlay network creation, and node labeling.
- **Storage:** Hetzner StorageBox integration using `davfs2`.
- **Directory Structure:** Creation of application and database-specific directories.
This establishes a comprehensive, automated pipeline for infrastructure deployment and initial configuration.
