refactor: Migrate frontend to use Vite and update testing framework

### Summary of Changes
- Replaced `react-query` with `@tanstack/react-query` in `package.json` and updated related imports.
- Updated frontend CI workflow to use `vitest` for testing instead of Jest, modifying test commands accordingly.
- Removed the `App.js`, `Dashboard.js`, `Settings.js`, and other component files, transitioning to a new structure.
- Enhanced error handling in the `useServiceStatus` hook to provide more informative error messages.

### Expected Results
- Improved performance and modernized the frontend build process with Vite.
- Streamlined testing setup with `vitest`, enhancing test execution speed and reliability.
- Increased clarity and maintainability of the codebase by adhering to clean code principles and removing unused components.
