fix: resolve ansible-lint errors

- Quote octal file mode values (0640, 0750 -> '0640', '0750')
- Add 'Prepare' name to prepare.yml play
- Fix truthy value in .gitea/workflows/test.yaml (on -> 'on')
- Use role name 'bind9' instead of path in converge.yml
- Move tags to top-level for Deploy and Validate Configuration block
- Remove unnecessary comments to clean up code
- Ensure all YAML and Ansible files pass ansible-lint production profile
