🔧 Fix TypeScript implicit any type errors

## 🎯 TypeScript Fixes
- ✅ Fix implicit 'any' type in admin-page-views route reduce function
- ✅ Fix implicit 'any' type in admin tests results route filter/reduce functions
- ✅ Fix implicit 'any' type in admin users route map function
- ✅ Fix implicit 'any' type in internships my-applications route map function
- ✅ Fix implicit 'any' type in health-checks monitoring map function
- ✅ Fix implicit 'any' type in audit-logger service forEach functions

## 📊 Results
- ✅ All TypeScript compilation errors resolved
- ✅ Proper type annotations added for better type safety
- ✅ CI/CD pipeline should now pass TypeScript checks
- ✅ Maintains functionality while improving code quality
