system-monitor: Workspace/Panel layout with a scope list (bTop / pm2 / dockers)
/system-monitor is now a WorkspaceView (like /music): a left ScopeList panel selects the scope over the 'monitor:scope' channel, the right MonitorMain panel renders it. Three scopes: - bTop — the existing system snapshot (CPU/mem/disks/top processes) - pm2 processes — new GET /api/system-monitor/pm2 (pm2 jlist → name/status/cpu/ mem/restarts/uptime table) - dockers — new GET /api/system-monitor/docker (docker ps → container cards with state/status/image/ports) Both new endpoints degrade gracefully to an error field. Persisted as screens/system-monitor; owner-only. Needs a restart (backend routes + rebundle) + hard-refresh to appear. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
