Update environment variable for S3 upload directory and enhance user data handling in UserListPage

- Removed the hardcoded S3 upload directory from .env.example and set default values for avatar, cover, and voiceBar in UserListPage to prevent undefined values.
- Updated AudioUpload and ImageUpload components to use default upload directories for better file organization.
