fix(log-drain): send Coolify labels to Fluent Bit drains

Containers without the Coolify default variables sent no project,
environment, or service to the drain. The fluentd driver now also sends
the Coolify container labels; the built-in configs use them as a
fallback and add coolify.service_name.

Closes #8415
