refactor: enhance CSS content retrieval in Vite config

- Updated the CSS content retrieval logic in `vite.standalone.config.ts` to dynamically find and read entry CSS files from specified directories, improving flexibility and maintainability.
- Removed hardcoded CSS file paths in favor of a directory-based approach, allowing for easier updates and better organization of CSS assets.
