Refactor Dashboard component to implement a structured routing system with dedicated pages for workplace input, login, chain selection, task management, and completion. Introduce centralized localStorage management for user data and navigation logic, enhancing user experience and streamlining the application flow. Remove the deprecated LoginForm component and update the MainPage to redirect users based on their authentication and task status.
