Changed from invalid '--vacuum=time:30d' to correct '--vacuum-time=30d'

Remove document separators (---) between plays in multi-play playbooks.
Ansible expects multiple plays to be in a single YAML document, not
separated by document delimiters.
Fixed files:
- remediate-storage-critical-issues.yml
- remediate-docker-storage.yml
- remediate-stopped-containers.yml
- configure-storage-monitoring.yml
All playbooks now pass ansible-playbook --syntax-check validation.

- Add MySQL host_vars with firewall rules for port 3306
- Enable IP forwarding on Docker hosts (hiveops, smartjournal)
- Fix container-to-external-network connectivity issue
The IP forwarding setting was previously disabled by the common role's
security defaults, preventing Docker containers from reaching external
databases. This change overrides that setting for hosts running Docker.

Proxmox uses its own firewall (pve-firewall) and doesn't need UFW.
This prevents accidental lockout of web UI (port 8006).
