Building on the existing admin dashboard structure at /admin, implement the full Admin Management functionality without impacting public routes. Add CMS-style management interfaces that allow authorized users to manage site content including pages (Home, About, Courses, 11+ Preparation, Franchise, Contact), courses, testimonials, and media assets, using editable forms with validation, publish/unpublish controls, and safe update handling. Implement enquiry management for parent enquiries and franchise applications, including status tracking (New, In Progress, Closed), internal admin notes, and filtering. Enforce role-based permissions, granting Admins full access and Editors restricted editing rights. Ensure all admin components are responsive, accessible, audit-safe, and designed for future CMS extensibility, while remaining strictly within the admin section of the existing project.
