Stacks page: table layout with usage meters, matching the dashboard (0.21.4)

The Stacks tab now lists stacks in the shared StacksTable (status, CPU
and memory meters, inline start/stop/restart) instead of cards, for both
the local host and per-agent sections — same look as the dashboard.
StacksTable gained optional showEdit/showDelete props so the management
surface keeps the Edit link and local Delete (with confirm). Search and
sort are unchanged. Removed the now-unused StackCard component.
