feat: implement web URL constants and enhance navigation handling

- Introduced a centralized `WEB_URL` constant for managing application routes, improving maintainability and readability across components.
- Updated various components, including login, auth, and main app modules, to utilize the new `WEB_URL` constants for navigation, ensuring consistency in route management.
- Added a new `AppHomeRedirect` component to streamline user redirection based on privileges, enhancing user experience.
- Implemented client-side navigation functions to prevent full page reloads, improving performance and user interaction.
- Added tests for new functionalities, ensuring reliability in navigation and URL handling.

These changes significantly enhance the application's routing structure and navigation efficiency, providing a more cohesive user experience.
