refactor: enhance ProtectedRoute and dashboard components for improved access control and user experience

- Updated the ProtectedRoute component to optimize access checking logic, preventing unnecessary re-checks and improving authentication flow.
- Enhanced the dashboard page to automatically open the login modal for authentication errors and refined loading states for better user feedback.
- Improved UI elements across various components for consistency and visual appeal, including updated tab styles and enhanced alert messages.
- Removed redundant footer from the vacation management page to streamline the interface.
