Server: the /companies/:companyId/live-runs endpoint now returns
issueId extracted from contextSnapshot, so the UI can match runs
to issues without N+1 queries.
UI (Issues.tsx): fetches company live runs (with 5s polling), builds
a set of issue IDs with active runs, and shows a pulsing "Live" badge
in each matching issue row — matching the existing blue live indicator
style from AgentDetail.
