fix: complete test suite fixes - achieve 99.8% pass rate

- Add missing lucide-react icons (Users, Target, MessageCircle, Layers, CreditCard)
- Fix admin/page.test.tsx ESLint errors (add displayName)
- Fix api/contact/route.test.ts ESLint errors (remove any types, use import)
- Add RESEND_API_KEY environment variable for API tests
- All 122 test suites now passing
- Test pass rate: 99.8% (1499/1502 passed, 3 skipped)
