feat(web): show sandbox status dot on the run overview panel

The Sandbox cell now renders a colored status dot before the resource
summary, with a tooltip explaining the state on hover. The dot reuses
the data already fetched for CPU/memory, so no new API call. Falls back
to the state label when resources are unavailable.

Lifts the per-state display map into a shared lib/sandbox-state module
so the overview panel and the dedicated sandbox page stay consistent.
