Refactor action and route handlers to use async schema validation (#361)

- Removed the `zodParseFactory` utility and replaced it with direct async schema validation using `safeParseAsync` in both `enhanceAction` and `enhanceRouteHandler`.
- Improved error handling to return meaningful messages for invalid request bodies.
- Streamlined the codebase by deleting the now-unnecessary `utils/index.ts` file.
