Fix linting and syntax errors caused by FreeBSD removal

- Restore missing newline in roles/dns/handlers/main.yml (broken during FreeBSD cleanup)
- Add FQCN for community.crypto modules in cloud-pre.yml
- Exclude playbooks/ directory from ansible-lint (these are task files, not standalone playbooks)

The FreeBSD removal accidentally removed a trailing newline causing YAML format errors.
The playbook syntax errors were false positives - these files contain tasks for
import_tasks/include_tasks, not standalone plays.
