chore: clean up dead barrels, duplicate config, and orphaned frontend components
Gateway:
- Remove dead barrels (ai-moderation/index, attachment-upload/index, message-capture/index) — all consumers import files directly
- Remove orphaned schema/ split dir (analytics/cache/messages/meta) — schema.ts is monolithic
- Merge duplicate config singleton: delete shared/config/config.ts, point all 44 imports at shared/config/index
Backend:
- Remove dead commandHelper.ts (voice-era fallback), ws/index.ts barrel, health.schema.ts, moderationMetrics.ts, analysis.schema.ts (0 importers; metrics/handlers route directly)
Frontend:
- Remove orphaned CategoryDrilldown/CoverageTiles/TopicTrends, primitives/slot, use-mobile, use-mounted
- Remove unused charts donut/sparkline (TopicTrends was only consumer)
Kept (verified active): shared/database/index.ts facade (11 importers), hooks/index + lib/api/index barrels (10 importers), orpc/ws.ts, charts/index.ts barrel.
Verified: tsc + biome + vitest per service (backend e2e 3 failures pre-existing on main); frontend next build 8 routes.
