feat(plan-13): read-only Ops Console (NestJS API + React UI) — Track 1

Real web Control Panel over CASAN harness telemetry (Level-3 casan-platform component).
Read-only ("Đọc ≠ Ghi"): no settings writes, no gate bypass. Management/RBAC/approval are
Track 2/3 (future, Plan-14). Additive — harness gate untouched (64/0/3).

packages/casan-control-panel/
- backend/ (NestJS, ESM, /api/v1 + ok() envelope): TelemetryReader (jsonl/json, missing→[],
  never fabricates) + TelemetryService (aggregations mirroring generate-agentops-dashboard.py)
  + endpoints overview/runs(+:traceId)/governance/security/incidents/tools/traceability/
  drift/cost, and /healthz (stale-aware 200/503, fail-loud like dashboard-server.py). App
  root + telemetry paths resolve via casan-paths-style marker walk-up (.specify OR
  packages/casan-harness) + honor CASAN_DASHBOARD_* env. Binds 127.0.0.1; refuses
  non-loopback under CASAN_PROFILE=prod. @Inject token so DI works under tsc AND tsx.
  Tests (node native runner) 7/0: reader parse/missing, app-root, overview shape on real
  repo state, freshness/stale fail-loud.
- frontend/ (React+Vite+Tailwind+TanStack, port 5174, proxies to :3010): AppLayout +
  Sidebar + Header (LIVE/STALE badge from /healthz) + pages Overview/Runs/Governance/
  Security/Incidents/Traceability. axios client unwraps ok() envelope. build green.

Wiring: root workspaces + `console:*` scripts. packaging/levels.json + casan-platform
README: platform preview now lists the Ops Console as an implemented component.

Verified: backend build + test 7/0; frontend tsc + vite build; API serves REAL data
(runs=6, provider_tokens=5556, action_blocks=7); /healthz 503 stale → 200 after touch.
