Phase 2: Admin UX - search/filter for awards, learning, partners pages

Phase 3: Dashboard - Recent Activity feed, Pending Actions card, quick actions

Phase 4: Jury - assignments progress/urgency, autosave indicator, divergence highlighting

Phase 5: Portals - observer charts, mentor search, login/onboarding polish

Phase 6: Messages preview dialog, CsvExportDialog with column selection

Phase 7: Performance - query optimizations, loading skeletons, useDebounce hook

Phase 8: Visual - AnimatedCard, hover effects, StatusBadge, empty state CTAs
