The dashboard now lists stacks in a table with live CPU and memory usage per
stack. Usage is sampled from docker stats (one-shot read per running container,
using the daemon-provided precpu for the CPU delta) and aggregated by compose
project.

- services/stats_service.py + GET /api/stacks/stats: per-stack cpu_used (cores),
  mem_used (bytes minus reclaimable cache), and the summed assigned cpu/mem
  limits (null when none set), read concurrently across containers.
- Dashboard: stacks render as a table with a CPU and a Memory meter. When a
  limit is assigned the bar fills toward it (used / limit + %); otherwise it
  fills toward the host total. Inline start/stop/restart per row for admins.
