Add dashboard summary view, server detail routing, and VM listing

Rearchitect to pure aggregator dashboard (no /proc) with bare agents
on each host. Agents report VM data via sudo virsh (cached 10s).
UI rewritten with hash-based routing: summary card grid and per-server
detail view with CPU grid, memory, load, uptime, and VM table.
