Refactor UUID generation, remove unused logger and encryption utilities, and clean up request handling
- Updated `generateUUID` function for improved readability and performance. - Deleted `logger.ts`, `other.ts`, `request.ts`, `storage.ts`, `tansParams.ts`, and `validate.ts` as they were no longer needed. - Simplified TypeScript configuration by removing unnecessary paths and aliases. - Enhanced Vite configuration for better project structure and maintainability.
