feat: Migrate frontend build tool from Vue CLI to Vite

This commit includes the necessary changes to migrate the web application's frontend build system from vue-cli to Vite.

Key changes include:
- Installed Vite and @vitejs/plugin-vue.
- Removed vue-cli dependencies.
- Created vite.config.js with configurations for aliases, proxy, and dev server, based on the previous vue.config.js.
- Moved public/index.html to web/index.html and updated it for Vite.
- Updated package.json scripts to use Vite commands.

Note: Due to persistent Node.js environment issues, I could not test the application after these changes. Manual testing and potential debugging will be required to ensure everything works as expected.
