fix: resolve all build errors for Vercel deployment

- Remove unused MCP server API routes (no longer needed)
- Remove /auth/callback/page.tsx (route conflict with route.ts)
- Wrap useSearchParams in Suspense boundary (Next.js 15 requirement)
- Add Organization export to cost-optimizer types
- Fix async cookies() calls for Supabase server client
- Simplify vercel.json configuration

Build passes with only deprecation warnings (metadata viewport).
