refactor: Enhance texture handling and configuration

- Removed Swagger documentation import from the main server file.
- Updated TextureInfo struct to include UploaderUsername for better texture metadata.
- Modified texture repository methods to preload Uploader information when fetching textures by hash.
- Improved texture service to handle cases where Uploader information is missing, ensuring proper caching and retrieval.
- Added Redis configuration options in the environment variable setup for better flexibility.
