🔧 Update Admin Dashboard and Authentication Flow

✅ Updated Admin Dashboard URL: - Changed the Admin Dashboard access path from `/admin` to `/manage` in multiple files for consistency. ✅ Enhanced Middleware Authentication: - Updated middleware to protect new admin routes including `/manage` and `/dashboard`. ✅ Implemented CSRF Protection: - Added CSRF token generation and validation for login and session validation routes. ✅ Introduced Rate Limiting: - Added rate limiting for admin routes and CSRF token requests to enhance security. ✅ Refactored Admin Page: - Created a new admin management page with improved authentication handling and user feedback. 🎯 Overall Improvements: - Strengthened security measures for admin access. - Improved user experience with clearer navigation and feedback. - Streamlined authentication processes for better performance.
