feat(milestone): merge phase/02 cohort-dashboard → milestone/v0.4-operator-tier
Phase 2 complete — Cohort Dashboard + Aggregation:
- Cohort aggregation pipeline (k-anon ≥10 write-time suppression, async hook, nightly 03:00 CT reconcile)
- 4 auth-gated operator API endpoints (cohort, mastery, failure-patterns, credentials)
- React cohort dashboard (BrowserRouter, login, 3 views, inline SVG sparklines, auth gate)
- SPA fallback via SpaStaticFiles subclass (G-041 — NOT catch-all route)
- G-038 differencing-attack test (unit + API e2e)
- 317 pytest pass, 36 skip, 0 fail; 17/17 vitest pass; npm build + typecheck clean
