Fix Role-Based Routing in Base44 App (React)

Seeking an experienced React developer to fix role-based routing issues in an existing Base44 application. The app must correctly route users based on their assigned roles (e.g., admin, landlord, tenant), ensuring each role lands on the appropriate dashboard and is restricted from unauthorized routes. Current issues include incorrect redirects, unprotected routes, and inconsistent navigation flow after login. The goal is to implement secure, reliable route protection, enforce proper access control at the component level, and optimize redirection logic for a smooth user experience. The solution must safeguard restricted pages, handle invalid or expired sessions gracefully, and maintain clean, maintainable routing logic within the Base44 and React environment.
