- Restructure security playbook with modular nftables loader
- Base rules loaded first, service rules second, drop rule last
- Add Gitea self-contained firewall management (port 2222)
- Add fail2ban protection for Gitea SSH brute force attacks
- Update documentation with new firewall architecture
- Create comprehensive Gitea deployment and testing guide
This enables self-contained service roles to manage their own firewall
rules without modifying the central security playbook. Each service
deploys rules to /etc/nftables.d/ which are loaded before the final
drop rule, maintaining the defense-in-depth security model.
