Fix: Update authentik Caddy template to use HTTP backend

- Change reverse_proxy from https:// to http:// backend
- Use authentik_http_port instead of authentik_https_port
- Remove unnecessary TLS transport configuration
- Remove health check for non-existent endpoint

This aligns the Ansible template with the working configuration
where authentik only serves HTTP internally and Caddy handles SSL.
