Subject: [PATCH] fix(api): respect service_name query param in application
 logs endpoint

GET /applications/{uuid}/logs ignored service_name and always returned
logs from the first container, so 'coolify app logs --service' could show
logs from the wrong Compose service. When service_name is present, select
the container whose labels contain the matching
com.docker.compose.service entry and 404 when nothing matches.
