Label all agentmon docker-compose services with agentmon.monitor=true
and agentmon.group=agentmon so the swarm-monitor picks them up.
Adds Group field to ServiceSnapshot, probes /healthz for api/web roles,
and renders a separate "Agentmon" section below Swarm Services on the
Infrastructure page with new api and worker card renderers.

- Active sessions query now finds truly active sessions (started
anytime, no session.end ever) instead of only today's sessions
- Use uPlot setData() for live WS updates instead of destroying
and recreating the chart on every event
- Destroy chart only on window change so it recreates with new scale
