Phase 6: Export & Polish — brand export, client dashboard, retention, analytics

- Brand-enforced export pipeline (PPTX/PDF with auto brand fonts/colors/logo)
- Client library dashboard with two-level navigation (client grid → detail tabs)
- Data retention service with ARQ cron jobs (daily cleanup + weekly purge)
- Brand-adaptive UI theme via CSS custom properties (dynamic per client)
- Analytics dashboard with overview, usage, quality, and performance metrics
