improve alloy config and match with main branch f2310f2b86 
- Restrict Alloy UI to loopback
- Narrow volume mounts: drop /dev, reduce /var/run to docker.sock:ro
- Replace HTTP scrape of :12345 with prometheus.exporter.self
Match with main branch (node-exporter / promtail / cadvisor):
- Add docker_only and explicit enabled_metrics to cadvisor exporter
- Match node-exporter collector config
- Match promtail relabeling (container_name, container_id, stack_namespace,
  service_name) and external hostname label
- Add SYSLOG_FILES option to tail /var/log/*log (matches promtail)
- Fix journal path and syslog listener address
feat: scrape metrics from containers via Docker label discovery e247677433 
Containers opt in with prometheus.io/scrape=true and optionally set
prometheus.io/port, prometheus.io/path, and prometheus.io/auth=basic.
feat: bearer auth support 64cb07a4a2
feat: enable alloy web ui fa76179987
feat: live debugging alloy 1970061ff8
fix: needed labels come from docker swarm d085c66d68
fix: send container metrics directly to prometheus 03227f1907
fix: filter by proxy network 23acf56637

i've been deploying this mainly for prometheus metrics and it's working great. i still have to test log ingestion. i'll need help with fixing the included grafana dashboards!
